The Endurance is in dire straits. She and her crew had sailed from the Island of South Georgia in December 1914, to land on the icy shores of Antarctica.

Now, months later, she is beset in the pack ice of the Weddell Sea. Ernest Shackleton, the famed Antarctic explorer, is in a struggle to free the ship before it's crushed and shipwrecked.

In the beginning days of World War I, the sailing ship Endurance had left England to sail to the distant Southern Ocean. Their task: A team of explorers were to cross the great unknown continent of Antarctica, a distance of 1,800 miles on foot, with sleds and dogs.

It was called the Imperial Trans-Antarctic Expedition. But at home, Great Britain, filled with excitement and anxiety over the coming war, had turned its attention away from this epic adventure.

As a result, the expedition was nearly forgotten. .

. The Endurance series, Book One, The Frozen Keep and Book Two, The Beckoning Shore, chronicles an amazing story of brotherhood, courage and survival that is unparalleled in the history of exploration.

Follow Ernest Shackleton, commander of the Imperial Trans-Antarctic Expedition, as his leadership skills are tested to the knife's edge on the high seas and in the vast, frozen wilderness of Antarctica. Watch as Jack Robinson and Leah Carlberg, two young teens, see their whirlwind romance torn apart by forces beyond their control.

While, a half world away, Jack's older brother Edward, struggles to survive on the battlefields of Europe in the Great War. .
