The best of all the Greeks strong, beautiful, and the child of a goddess Achilles is everything the shamed Patroclus is not. Yet despite their differences, the boys become steadfast companions. Their bond deepens as they grow into young men and become skilled in the arts of war and medicine much to the displeasure and the fury of Achilles’ mother, Thetis, a cruel sea goddess with a hatred of mortals.

Seduced by the promise of a glorious destiny, Achilles joins their cause, and torn between love and fear for his friend, Patroclus follows. Little do they know that the Fates will test them both as never before and demand a terrible sacrifice. Built on the groundwork of the Iliad , Madeline Miller page-turning, profoundly moving, and blisteringly paced retelling of the epic Trojan War marks the launch of a dazzling career.

Release stuck stress with MELT Over a decade ago, Sue Hitzmann was at the height of her career as an international fitness presenter and instructor. She appeared to be in perfect health, yet she was experiencing debilitating pain in her foot. With a master degree in exercise science and advanced training in neuromuscular therapy, she thought it would be easy to find out what was going on in her body, but even the most prominent doctors and physical therapists couldn't explain what was wrong. Although she was only in her twenties, Hitzmann career was threatened and her quality of life was in decline. Hitzmann learned the hard way that diet, exercise, and muscular strength are not the foundation of a healthy, pain-free body. As she sought the true source of her pain, she radically changed her focus from fitness to hands-on bodywork. In her quest to live an active, pain-free life, she became fascinated by the emerging science of connective tissue, or fascia, which surrounds all aspects of your body, including your muscles, bones, nerves, and organs. The researchers she met were discovering that connective tissue the system of the body that supports, protects, and stabilizes was responsive, adaptable, and renewable. What Hitzmann came to realize is that connective tissue dehydration is the underlying cause of the daily aches, stiffness, and strain that leads to pain, as well as weight gain, sleep problems, and many other seemingly unrelated issues. Through her personal exploration and private practice, she developed the MELT Method, and has since trained thousands of instructors in the science and application of Hands-Off Bodywork. MELT can help you fall asleep more easily and sleep more soundly, have more energy during the day, improve your posture, reduce stress and tension, shed excess body fat, and reduce cellulite. While it may seem too good to be true, it worked for more than 200,000 people so far. Translated into eight languages, The MELT Method is now helping people around the world. Live your best, most youthful and vibrant life possible. Free yourself of chronic pain and be healthy and active with MELT!

In combat, men measure up. Or don't. There are no second chances. In this vivid account of the U.S. Army's legendary 10th Mountain Division's heroic stand in the mountains of Afghanistan, Captain Sean Parnell shares an action-packed and highly emotional true story of triumph, tragedy, and the extraordinary bonds forged in battle. At twenty-four years of age, U.S. Army Ranger Sean Parnell was named commander of a forty-man elite infantry platoon a unit that came to be known as the Outlaws and was tasked with rooting out Pakistan-based insurgents from a mountain valley along Afghanistan's eastern frontier. Parnell and his men assumed they would be facing a ragtag bunch of civilians, but in May 2006 what started out as a routine patrol through the lower mountains of the Hindu Kush became a brutal ambush. Barely surviving the attack, Parnell's men now realized that they faced the most professional and seasoned force of light infantry the U.S. Army had encountered since the end of World War II. What followed was sixteen months of close combat, over the course of which the platoon became Parnell's family: from Staff Sergeant Greg Greeson, the wise, chain-smoking veteran who never lost his cool; to Specialist Robert Pinholt, a buttoned-down conservative with the heart of a warrior and the mind of an economist; to Staff Sergeant Phil Baldwin, the platoon's voice of calm and reason, a man who sacrificed everything following the events of 9/11 career, home, financial stability to serve his country. But the cost of battle was high for these men: Over 80 percent were wounded in action, putting their casualty rate among the highest since Gettysburg, and not all of them made it home. A searing and unforgettable story of friendship in battle, Outlaw Platoon brings to life the intensity and raw emotion of those sixteen months, showing how the fight reshaped the lives of Parnell and his men and how the love and faith they found in one another ultimately kept them alive.
