New York Times bestselling author Mark Synnott has free climbed with Alex Honnold. He's scaled Mt. Everest. But in 2022, he realized there was a dream he'd never conquered, never mind attempted-to sail the Northwest Passage in his own boat, a feat only 400 or so sailors had ever accomplished-and in doing so, try to solve the mystery of what happened to legendary 19th century explorer Sir John Franklin and his ship, the HMS Terror.

New York Times bestselling author Mark Synnott has climbed with Alex Honnold. He's scaled Mount Everest. He's pioneered big-wall first ascents, including the north-west face of the mile-high Great Trango Tower, and skied monster first descents. But in 2022, he realized there was a dream he'd yet to achieve- to sail the Northwest Passage in his own boat-- a feat only four hundred or so sailors have ever accomplished-and in doing so, try to solve the mystery of what happened to legendary nineteenth-century explorer Sir John Franklin and his ships, HMS Erebus and Terror.

Only a few hundred vessels have ever transited the Northwest Passage, and substantially fewer have done so in a fiberglass-hulled boat like Polar Sun. But Mark was determined to return to the Arctic, where he cut his teeth as a young climber, and in the process investigate one of the great mysteries of exploration- What really happened to Sir John Franklin and his entire 128-man crew, which disappeared into these ice-strewn waters 175 years ago?

In this pulse-pounding travelogue, Mark Synnott paints a vivid portrait of the Arctic, which is currently warming twice as fast as any other part of our planet. He weaves its history and people into the first-person account of his epic journey through the Northwest Passage, searching for Franklin's tomb along the way-- all while trying to avoid a similar fate.

In Into the Ice, Mark and his crew race against time and treacherous storms in search of answers to the greatest mystery of all time- What is it that drives someone to risk it all in the name of exploration?
