About The Book

Jonah and Katherine embark on a chilling journey to discover the Northwest Passage in this new installment of the New York Times bestselling series that brings history to life.

Teenager John Hudson vanished from history in 1611: While searching for the Northwest Passage, mutineers cast him and his explorer father adrift in the icy waters of James Bay. When Jonah and Katherine meet John in the past, moments before the mutiny is to occur, they think it will be easy to rescue him from history. But the unexpected appearance of a man who claims to know a secret route to the Northwest Passage complicates matters. He seems serious about leading the ship further west, but Jonah and Katherine grow more and more suspicious—and more and more frustrated that they can’t quite remember the actual history or Canadian geography. And when their former enemies, Gary and Hodge, show up, apparently having escaped from time prison, Jonah and Katherine understand that a lot more is at stake than just one boy’s life….

About the Book

In this fourth entry in The Missing series, Jonah and Katherine barely have a chance to recover from the traumatic events in Roanoke in 1600 when they are hurtled through time again, moments before a mutiny aboard the Discovery, Henry Hudson’s ship, in the icy waters of James Bay. As they struggle to survive the frozen seas and brutal conditions aboard the ship, Jonah and Katherine realize that something is terribly wrong. The history they remember is drastically different from what they are experiencing. Will this new version of history replace the past? Jonah and Katherine struggle to unravel the mysteries of 1611 and the mysteries about the Hudson Passage before the only future they have ever known is lost forever.
