Bella Bathurst’s epic story of Robert Louis Stevenson’s ancestors and the building of the Scottish coastal lighthouses against impossible odds. ‘Whenever I smell salt water, I know that I am not far from one of the works of my ancestors,’ wrote Robert Louis Stevenson in 1880. ‘When the lights come out at sundown along the shores of Scotland, I am proud to think they burn more brightly for the genius of my father!’ Robert Louis Stevenson was the most famous of the Stevensons, but not by any means the most productive. The Lighthouse Stevensons, all four generations of them, built every lighthouse round Scotland, were responsible for a slew of inventions in both construction and optics, and achieved feats of engineering in conditions that would be forbidding even today. The same driven energy which Robert Louis Stevenson put into writing, his ancestors put into lighting the darkness of the seas. ‘The Lighthouse Stevensons’ is a story of high endeavour, beautifully told; indeed, is was one of the most celebrated works of historical biography in recent memory. ‘My own interest in the Lighthouse Stevensons is threefold. Firstly, from the writings of Robert Louis Stevenson, who turned his family’s trade into the raw gold of all his best fiction. Secondly, from various trips around Scotland. The country’s coast is a mass of storm-beaten rocks and treacherous headlands on which even the seagulls have trouble landing. It is impossible not to speculate what combination of courage and skill built the lighthouses around such an environment. And thirdly, because somewhere in there, unrecognised and unsung, is the most wonderful story!’

A vivid retelling of the Battle of Waterloo, based on unpublished soldiers’ written accounts. When a patriotic model-maker recorded the days’ events for posterity he left us with a glorified version of an English victory. Malcolm Balen brings us the muddy truth. More than fifty thousand died or were wounded on the single bloody day of the Battle of Waterloo. This was killing on the scale of the First World War, and yet the glory of the British victory soon came to overshadow any notion of its gore. In this electrifying account of the day itself, Malcolm Balen combines extraordinary first-hand accounts of the battle with the story of William Siborne, a model-maker who, in the wake of the battle, wanted to leave to posterity a perfect and accurate representation of the crucial moment in the battle. The question was: Who won it? Was it Wellington’s forces or Blucher’s Prussians, or a combination of the two? The accounts Siborne used to piece the muddy truth together read as if Waterloo had been fought yesterday. But the accuracy he relentlessly pursued came up against the British establishment and the Duke of Wellington’s desire to control the narrative of the day. In this fascinating and refreshing account of one of the bloodiest days in history, Malcolm Balen interweaves two battles fought: one in the muddy fields of Belgium, and the other over history itself.

This New Naturalist volume provides a much-anticipated overview of these fascinating birds – the first book on the natural history of British and Irish terns since 1934. Terns are small seabirds that are commonly seen along coastlines and estuaries in the summer months – their graceful flight and command of the air are among their most attractive features. Most of the five species of terns breeding in Britain and Ireland today are under intensive management, involving protection from predators, human interference, egg-collecting, recreational activities, land-use changes, and a range of issues concerning climate change, including rising sea levels and flooding of low-lying colonies. If these protective measures were abandoned then the numbers of terns would inevitably decline, with the possibility of several species ending up on the endangered list. Covering the history of terns in Britain and Ireland, David Cabot and Ian Nisbet explore these diverse issues as well as offering a comprehensive natural history of these stunning seabirds. Drawing on a wealth of new information and research, the authors focus on migrations, food and feeding ecology as well as breeding biology and behaviour. Perhaps most importantly, they highlight recent conservation issues and prospects, and what this means for the future of terns.

With his groundbreaking findings and extensive research, palaeontologist and dino hunter Dr Phil Currie challenges the very foundations of traditional dinosaur theories. Seventy million years ago the Mongolian desert was home to the world's biggest, most dangerous carnivores – 5 meters tall, 12 meters long and weighing over 4 tonnes, the Tyrannosaurs were the most formidable hunters to walk the earth. Now, new research emerges that threatens to challenge the foundation of many traditional theories on the biology of these fascinating creatures. Palaeontologist and dino hunter Dr Phil Currie is out to prove how dinosaurs actually lived. He and his team have been searching for the fossilised truth about dinosaurs in the most extreme conditions; searing 40 degree heat, intense sandstorms and the constant threat of illegal poachers. Currie's groundbreaking investigation takes him from Mongolia to Canada and Patagonia in search of new evidence. He is looking for one dinosaur in particular, the ‘Tarbosaurus bataar’ which he believes will lead him to prove that the world's first pack hunters existed millions of years ago, but he also stumbles upon the many new truths behind these mythical animals. ‘Dino Gangs’ contains their exclusive, groundbreaking scientific research that has finally resolved the extraordinary biology of these awe-inspiring creatures.

Recommended for viewing on a colour tablet. The Collins New Naturalist series is the longest-running and arguably the most influential natural history series in the world with over 120 volumes published in nearly 70 years. Being a numbered series, with a very low print run for some volumes, New Naturalist publications have been and continue to be highly collectable. Second-hand copies of the rarer volumes, in very good condition, can command high prices. As such, there is considerable interest in a detailed bibliography and history of the series. Collecting the New Naturalists offers a detailed insight into the fascinating phenomenon that has gripped Britain since just after World War II and which reflects the country’s continued enthusiasm for wildlife and nature publishing generally. With previously unpublished in-depth insight into the workings of the series and its collectors, the book will comprehensively cover every aspect of the New Naturalists, from rare editions produced for Bloomsbury and the Reader’s Union to foreign editions, interviews with the iconic cover artists and well-known naturalists such as Nick Baker and Alan Titchmarsh telling the story of their own fascination with the series.

An authoritative and radical rethinking of the history of Ancient Britain and Ancient Ireland, based on remarkable new archaeological finds. British history is traditionally regarded as having started with the Roman Conquest. But this is to ignore half a million years of prehistory that still exert a profound influence. Here Francis Pryor examines the great ceremonial landscapes of Ancient Britain and Ireland – Stonehenge, Seahenge, Avebury and the Bend of the Boyne – as well as the discarded artefacts of day-to-day life, to create an astonishing portrait of our ancestors. This major re-revaluation of pre-Roman Britain, made possible in part by aerial photography and coastal erosion, reveals a much more sophisticated life in Ancient Britain and Ireland than has previously been supposed. This edition does not include illustrations.

After decades of service and years of watching her family's troubles splashed across the tabloids, Britain's Queen is beginning to feel her age. She needs some proper cheering up. An unexpected opportunity offers her relief: an impromptu visit to a place that holds happy memories—the former royal yacht, Britannia, now moored near Edinburgh. Hidden beneath a skull-emblazoned hoodie, the limber Elizabeth (thank goodness for yoga) walks out of Buckingham Palace into the freedom of a rainy London day and heads for King's Cross to catch a train to Scotland. But a characterful cast of royal attendants has discovered her missing. In uneasy alliance a lady-in-waiting, a butler, an equerry, a girl from the stables, a dresser, and a clerk from the shop that supplies Her Majesty's cheese set out to find her and bring her back before her absence becomes a national scandal.Mrs Queen Takes the Train is a clever novel, offering a fresh look at a woman who wonders if she, like Britannia herself, has, too, become a relic of the past. William Kuhn paints a charming yet biting portrait of British social, political, and generational rivalries—between upstairs and downstairs, the monarchy and the government, the old and the young. Comic and poignant, fast paced and clever, this delightful debut tweaks the pomp of the monarchy, going beneath its rigid formality to reveal the human heart of the woman at its center.

After her young nephew and two nieces’ parents are drowned in a tragic sailing accident off the coast of Cornwall, the beautiful red-headed Tamara is devastated by their loss and realises almost at once that she is the only person who can look after the three children as she loves them so much. She speaks to the local Solicitor, who tells her that there is no money left in her brother-in-law’s estate and so she has no choice but to take the three children to their uncle, the Duke of Granchester, who lives in splendid isolation in a vast sprawling but intimidating Castle in Gloucestershire. The prospect at once appals Tamara. Firstly because she despises the Duke for the way he had cut off all contact with her sister and brother-in-law as he disapproved of their marriage, thinking that she was an actress when in fact she was a renowned opera singer. Worse still, Tamara has written a somewhat scurrilous novel portraying the Duke as the vile character she believes him to be! And the novel is just about to be published in London! Arriving at Granchester Castle in the guise of the children’s Governess, she finds the Duke to be as arrogant, high-handed and annoyingly handsome as her fictional portrayal of him and she hates him even more bitterly. Until a touch of love intervenes and changes everything forever.

One in three girls will be in a controlling, abusive dating relationship before she graduates from high school – from verbal or emotional abuse to sexual abuse or physical battering. Is your daughter in dangerDr. Jill Murray speaks on the topic of dating violence at high schools around the country, reaching more than 10,000 students, teachers, and counsellors each year. In every school she visits, she is approached by teenage girls in miserable relationships who, when confronted with the option of breaking up with the boy, exclaim, "But I love him!" Many young women and their parents, aren't even aware of the indications of a potentially abusive relationship. What's most alarming is that these warning signs are also some of the behaviours that girls find most flattering: A boy pages and calls a girl often but as a form of control, not affection. He wants to spend all his time with her, but eventually won't allow her to spend time with her friends. He says "I love you" very early in the relationship. These behaviours can escalate into blaming, isolating, manipulating, threatening, humiliation, and sexual and physical abuse. In But I Love Him, Dr. Murray identifies these controlling, abusive patterns of behaviour and helps you get your daughter out of the relationship without alienating her. You will learn what draws her to this type of relationship, why she has a hard time talking to you about it, the special barriers teens face when breaking off a relationship, and what's going on in the mind of a teen abuser. Dr. Murray will help you show your teen what a respectful relationship looks like, and teach her the importance of respecting herself. edition.
