Time Castaways #3: The Forbidden LockHardcover, 13 October 2020

In this action-packed conclusion to the Time Castaways series from Liesl Shurtliff, New York Times bestselling author of Rump, it's up to the Hudson kids to defeat Captain Vincent once and for all. With magic, mystery, and adventure, this series is perfect for fans of Escape from Mr. Lemoncello's Library and Percy Jackson.

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, Captain Vincent will soon be able to erase people from time altogether--including those pesky Hudson kids.

Mass chaos unfolds as time periods begin crashing into one another. Central Park becomes a playground for dinosaurs. The Metropolitan Museum of Art is overrun by the very historical figures it features. And the Hudsons begin to disappear, one by one, and Matt finds himself increasingly alone.

But hope comes from an unexpected source: a Vermillion rebel and Hudson ally has been keeping her own timeline a secret. A race to the Forbidden City reveals that Captain Vincent broke the lock on the three pillars of the universe--matter, space, and time--that created order in the world.

Only the Hudson kids are able to mend what he broke...and the key is in 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.
