The highly praised biography of an archetypal great house and the family who lived there for over 250 years. ‘The Big House’ is the biography of a great country house and the lives of the Sykes family who lived there, with varying fates, for the next two hundred and fifty years. It is a fascinating social history set against the backdrop of a changing England, with a highly individual, pugnacious and self-determining cast, including: ‘Old Tat’ Sykes, said to be one of the great sights of Yorkshire (the author’s great-great-great-grandfather), who wore 18th-century dress to the day of his death at ninety-one in 1861. His son was similarly eccentric, wearing eight coats that he discarded gradually throughout the day in order to keep his body temperature at a constant. He was forced to marry, aged forty-eight, eighteen-year-old Jessica Cavendish-Bentick – a lively and highly intelligent woman who relieved the boredom of her marriage by acquiring a string of lovers, writing novels and throwing extravagant parties (her nickname became ‘Lady Satin Tights’), all the while accumulating debts that ended in a scandalous court case. Their son, Mark, died suddenly whilst brokering the peace settlement at the Paris Peace Conference at the end of World War I; Sledmere was destroyed by fire shortly afterwards. But the rebuilt Sledmere rose from the flames to resound again with colourful, brilliant characters in the 1920s and 1930s including the author’s grandmother, Lily, who had been a celebrated bohemian in Paris. ‘The Big House’ is vividly written and meticulously researched using the Sykes’ own family’s papers and photographs. In this splendid biography of place and time, Christopher Simon Sykes has resuscitated the lives of his ancestors and their glorious home from the 18th- through to the 20th-century.

Penelope Fitzgerald’s fascinating portrait of the tragic poet and her life at the heart of the Bloomsbury set. Charlotte Mew (1869-1928) cut one of the most distinctive figures of the twentieth century – beloved of Siegfried Sassoon and Walter de la Mare (for whom she was ‘a very rare being’), unafraid of Virginia Woolf, and considered by Hardy to be ‘far and away the best living woman poet’. Part of a new wave of fashionable female dandies who lived passionate, precarious existences in Bloomsbury, she was an enchanting and spirited personality. But behind the brave face was a life riddled with grief: left to care for her disturbed mother, two siblings with undiagnosed Schizophrenia and Charlotte herself burdened by depression and closeted lesbianism; she killed herself by drinking household disinfectant. In this unexpectedly gripping portrait of a life of passion unfulfilled, Penelope Fitzgerald brings all her novelist’s skills into play in telling a story that is at once tragic, beautiful and deeply human.

Datele prezentate acoper? practic toate Aspectele vie?ii politice, sociale, economice ?i culturale ale acestui interval de timp, marcat at?t de aura ?arilor, c?t ?i de nenum?ratele revolte populare.

O istorie politico-sentimental? a capitalei noastre. De ce o istorie politico-sentimental?? Pentru c?, ?n evolu?ia Bucure?tiului, de-alungul secolelor, afacerile politice s-au ?mpletit adesea, inevitabil, cu b?t?ile inimii. Chiar prima perioad? a cet??ii, ca ?i capital? domneasc?, tutelat? de figu ra dominant? a doamnei Chiajna, poate fi b?nuit? de un senzualism crud care a deschis drum acelui fenomen pe care Ionescu-Gion ?l numea at?t de plastic ?ginecolatrie“, adic? ascultarea dovedit? de domnitorii valahi fa?? de so?iile lor.

C?teva dintre calit??ile pe care eu le apreciez cel mai mult la o carte sunt simplitatea scriiturii, lipsa de preten?ii intelectuale (prin intermediul c?rora autorul ar vrea s? arate c?t e el de de?tept) ?i naturale?ea textului, adic? autenticitatea. ?#confuz” are toate aceste calit??i. ?n plus, cartea mai beneficiaz? de c?teva atuuri foarte importante: povestea este una universal?, plin? de ?nt?mpl?ri credibile, care se pot ?nt?mpla oric?rui om ?i care pot avea loc oriunde ?n lume, iar scriitura are o oralitate u?or de identificat ?nc? de la primele pagini. (Adrian Tele?pan) ?#confuz” nu e o carte despre homosexualitate. E o carte despre oameni. Despre drumul fiec?ruia spre el ?nsu?i. Despre puterea de a accepta ce g?se?ti atunci c?nd ajungi la tine. Despre a nu te (mai) min?i. Nu atunci c?nd e?ti singur ?i gol ?i te prive?ti ?n ochii sufletului. Pentru c?, atunci, nu ?i vei mai min?i nici pe al?ii. Iar ?sta e primul pas spre asumare. ?i numai a?a vei putea fi fericit. ?#confuz” e o carte despre fericire. Copile, via?a e prea scurt? pentru a fi nefericit. Vrei s? fii o alt? umbr? care trece indiferent? prin via??? (Laura Nureldin) ?ti?i melodiile alea pe care le auzi o singur? dat? ?i te treze?ti fredon?ndu-le o or? mai t?rziu? E semn c? au intrat ?n tine. Cam a?a e ?i cu cartea asta. Nu e Beethoven. E un c?ntec care pare n?scut la o chitar?, pe plaj?, l?ng? un foc de tab?r?, sub luna plin?. ?l ascul?i z?mbind ?i ??i d? o stare de plin. ??i r?m?ne pe piele ca ni?te fire de nisip. G?ndul nu ??i fuge ?n alt? parte. E?ti acolo, ascul?i ?i admiri sinceritatea omului care improvizeaz? la chitar? f?r? s? ?ncerce s? ??i demonstreze nimic. C?nt? liber despre ceva-ul lui, timpul trece pe nesim?ite, s?dind ?n tine o senza?ie de bine. S? mai c?n?i, Alex! S? mai c?n?i! (Natalie Ester) Dincolo de sui?uri ?i cobor??uri, de momente-surpriz? ?i certuri interminabile, de scene erotice pasionale ?i absurd cotidian, acest roman e un incredibil de reu?it portret al energiei s?lbatice, al confuziei mascate ?n obstina?ie, pe care numai la 20 de ani o po?i tr?i. ?i tu, drag? cititorule, ai fost confuz odat?. ?i ce bine a fost. Lectur? pl?cut?. (Lorena Lupu)

Rendhagyó útinapló egy egzotikus világról és a n?i lélekr?l Akkor kezdtem ábrándozni a ?sz?késr?l”, amikor gyerekkoromban beszereztem egy már akkor is ciki pálmafás-tengerpartos posztert a zsebpénzemb?l, és felragasztottam a gyerekszobám falára, nem zavartatva magam szüleim d?bbent pillantásától. Attól kezdve a téli estéken odaképzeltem magam a kókuszpálma alá, ahol h?ség van, és – bár akkor még nem jártam tengerparton – szinte hallottam a tenger zúgását, egészen elalvásig. Elérkezett az id?, hogy beváltsam a magamnak tett ígéretet, és teljesülj?n a gyerekkori álmom: néhány éve télen ?megsz?ktem” kedvenc városomba, Bangkokba, és k?rbeutaztam Délkelet-?zsiát. Találkozásokról, naplementékr?l, ázsiai mesékr?l és elképeszt? sorsokról, egzotikus nagyvárosi lüktetésr?l, lakatlan szigetekr?l és egy másfajta életszemléletr?l szól ez a k?nyv, amit egy thai pálma alatt kezdtem írni. ?t forró, napsütéses téli hónap alatt sokat tanultam, és szinte minden megváltozott bennem és k?rül?ttem: a sors akaratából megtanultam elengedni, sorsfordító d?ntéseket hoztam, szembenéztem ?nmagammal, az újságíróval, a n?vel, az emberrel, mint talán még soha azel?tt. Ez a k?nyv nem a képzelet szüleménye, de ahányszor beleolvasok, a képzeletemben újra utazom, újra ott vagyok azok k?z?tt az emberek k?z?tt, akikt?l meg lehet tanulni ?LNI. Csupa nagybet?vel.
