Time Castaways: The Forbidden Lock

The time travelling Hudson kids face their ultimate adventure as epochs crash together in the middle-grade fantasy series finale.

With the power of the Aeternum, Captain Vincent can rewrite history to create his perfect future. And thanks to Alfred Nobel, the notorious inventor of dynamite, he will soon be able to erase people from time altogether—including those pesky Hudson kids.

As Captain Vincent unleashes temporal chaos, Central Park becomes a playground for dinosaurs and the Metropolitan Museum of Art is overrun by the very historical figures it features. Meanwhile, the Hudsons begin to disappear, one by one, and Matt finds himself increasingly alone.

Only the Hudson kids are able to mend the three pillars of the universe—matter, space, and time—that Captain Vincent broke. And to do it they must return to Matt’s birthplace, Ciudad Perdida, the Lost City of Colombia, where the Hudsons and Captain Vincent face off in the ultimate showdown—a battle for time itself.
