Still reeling from their experiences in Roanoke in 1600, Jonah and Katherine arrive in 1611 only moments before a mutiny on Henry Hudson’s ship in the icy waters of James Bay. But things are messed up: they’ve lost the real John Hudson, and they find what seems to be the fabled Northwest Passage—even though they are pretty sure that that route doesn’t actually exist. Will this new version of history replace the real past? Is this the end of time as we know it? With more at stake than ever before, Jonah and Katherine struggle to unravel the mysteries of 1611 and the Hudson Passage...before everything they know is lost.I love Haddix’s The Missing series. It’s awesome time travel with a liberal dash of historical biography. Add in characters that are written to be children but still connect with the reader and you have a great series. This latest book in the series doesn’t disappoint either. I like how it tells the tale of something more obscure than the first two travel stories. I had heard of the princes in the tower and Roanoke colony, but I had never known a boy was lost with Hudson. Jonah has a starring role in this story as he takes the place of John, and he develops as a character much as Katherine did in Missing. The plot is intriguing, and the fact that most of the story happens on one close boat makes it even more exciting because there’s not far for any of the characters to go or for Jonah and Katherine to maneuver around problems. The result is a tight, logical progression that has good character development and a great voice. Although the ending made it seem that the series could be over there are plans for more books, so I’ll let Jonah and Katherine enjoy their short rest before we have more educational history adventures.
