In January 1915, after battling its way through a thousand miles of pack ice and only a day's sail short of its destination, the Endurance became locked in an island of ice. Thus began the legendary ordeal of Shackleton and his crew of twenty-seven men. When their ship was finally crushed between two ice floes, they attempted a near-impossible journey over 850 miles of the South Atlantic's heaviest seas to the closest outpost of civilization. In Endurance , the definitive account of Ernest Shackleton's fateful trip, Alfred Lansing brilliantly narrates the harrowing and miraculous voyage that has defined heroism for the modern age.","forthcoming":false,"isbn13":"9780465062881","publication_date":"20150428","publisher":"Basic Books","slug":"endurance","subtitle":"Shackleton's Incredible Voyage","title":"Endurance"},"discovery":{"categories":{"all":[{"bisac_code":"TRA006010","confidence_band":"medium","label":"Maritime History","score":0.7621,"source":"bisac_hint_model"},{"bisac_code":"NAT045030","confidence_band":"medium","label":"Polar Worlds","score":0.7499,"source":"bisac_hint_model"},{"bisac_code":"HIS027150","confidence_band":"medium","label":"Naval History","score":0.6933,"source":"bisac_hint_model"}],"hint":[{"bisac_code":"TRA006010","confidence_band":"medium","label":"Maritime History","score":0.7621,"source":"bisac_hint_model"},{"bisac_code":"NAT045030","confidence_band":"medium","label":"Polar Worlds","score":0.7499,"source":"bisac_hint_model"},{"bisac_code":"HIS027150","confidence_band":"medium","label":"Naval History","score":0.6933,"source":"bisac_hint_model"}],"publisher":[{"bisac_code":"BIO023000","confidence_band":"high","label":"Adventurers & Explorers","score":1,"source":"onix_publisher_code"},{"bisac_code":"HIS046000","confidence_band":"high","label":"Polar Regions History","score":1,"source":"onix_publisher_code"},{"bisac_code":"HIS051000","confidence_band":"high","label":"Exploration & Discovery","score":1,"source":"onix_publisher_code"},{"bisac_code":"TRA006010","confidence_band":"high","label":"Maritime History","score":1,"source":"onix_publisher_code"}]},"genres":[{"label":"Maritime History","score":0.7621,"slug":"maritime-history"},{"label":"Polar Worlds","score":0.7499,"slug":"polar-worlds"},{"label":"Naval History","score":0.6933,"slug":"naval-history"}],"reader_fit":["Good for readers interested in true survival stories","Good for fans of historical maritime adventures"],"related_lists":[],"series":null,"similar_books":[{"authors":["Nathaniel Philbrick"],"book_id":"9780141001821","cover_image_url":"https://img.bookfrontier.com/9780141001821.jpg?v=20260414T102527Z%3A2026-04-14T10%3A25%3A27Z","score":19.2851,"title":"In the Heart of the Sea","url":"https://bookfrontier.com/books/9780141001821"},{"authors":["Mitchell Zuckoff"],"book_id":"9780062133403","cover_image_url":"https://img.bookfrontier.com/9780062133403.jpg?v=20260414T102527Z%3A2026-04-14T10%3A25%3A27Z","score":14.0733,"title":"Frozen in Time","url":"https://bookfrontier.com/books/9780062133403"},{"authors":["Hampton Sides"],"book_id":"9780525565703","cover_image_url":"https://img.bookfrontier.com/9780525565703.jpg?v=20260414T102527Z%3A2026-04-14T10%3A25%3A27Z","score":12.6397,"title":"The Wide Wide Sea","url":"https://bookfrontier.com/books/9780525565703"},{"authors":["David Grann"],"book_id":"9780307742490","cover_image_url":"https://img.bookfrontier.com/9780307742490.jpg?v=20260414T102527Z%3A2026-04-14T10%3A25%3A27Z","score":12.3656,"title":"The Wager","url":"https://bookfrontier.com/books/9780307742490"},{"authors":["John U.
