The chupacabras of the Râio Grande

Pura Belpre 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?
