Elliot and Uchenna have barely recovered from their first adventure with the Unicorn Rescue Society when the mysterious Professor Fauna approaches them with an all-new quest. And this time, they're going to have to cross the Atlantic Ocean to the Basque Country of northern Spain. Elliot and Uchenna, with Jersey in tow, soon wonder whether their newest, fire-breathing rescue might be more than they can handle. And why do the evil-doing Schmoke Brothers seem to be involved yet again?

This is the second book in Unicorn Rescue Society, an exciting and hilarious new series about friendship, adventure, and mythical creatures from around the world by Newbery Honor-winning author Adam Gidwitz teamed up with Mixtape Club founders Jesse Casey and Chris Smith, and Hatem Aly, illustrator of The Inquisitor's Tale.
