Pura Belpré Honor-winning author David Bowles joins Newbery Honor-winning Adam Gidwitz as co-author of the newest Unicorn Rescue Society adventure, as the kids travel to the U.S.-Mexican border to help the legendary chupacabras.

A new adventure begins for Elliot and Uchenna when Professor Fauna bursts into their classroom with
a frightening report from the Texas-Mexico border: something has completely drained the blood from
a cow’s body! The team must fly to Laredo, where tempers are running high.
 
Teaming up with local kids Lupita and Mateo—plus their brilliant mother, Dr. Alejandra Cervantes, and her curandero husband, Israel—can the Unicorn Rescue Society save the region’s animals and help bring a divided community together once more? And what is that spiny, bloodsucking, adorable little creature?
