Across the vast, blue ocean, in the mountains of the Basque Country, a fearsome creature has gone missing. And the Unicorn Rescue Society are the only ones who can save it.

Elliot and Uchenna--and Jersey --have barely recovered from their first adventure with Professor Fauna when he approaches them with an all-new quest. Except this time they're going to have to cross an ocean. In the mountains of the Basque Country, the Unicorn Rescue Society must track down a missing dragon. But how could someone even kidnap a dragon? And for what evil purpose? And is their newest, fire-breathing rescue more than they can handle?

New challenges await in this second book in the Unicorn Rescue Society series, a brand-new fantasy-adventure from Adam Gidwitz, the beloved bestselling and Newbery Honor-winning author of The Inquisitors Tale and A Tale Dark & Grimm. Illustrated throughout, it's the perfect fit for newly independent readers looking for a story full of adventure, fun, and friendship.
