When Uchenna and Elliot's classmate publishes an article in the school newspaper about the Schmoke Brothers, Professor Fauna notices something alarming in a photo. Mounted on the wall of the Schmoke's living room is a single spiral horn that he's certain could have come from only one animal--a unicorn! To save these magical creatures--and to finally see a unicorn themselves--the Unicorn Rescue Society heads to the rugged mountains of Pakistan.

Hena Khan, the critically acclaimed author of Amina's Voice, joins Newbery Honor-winner Adam Gidwitz for the Unicorn Rescue Society's most dramatic, action-filled mission yet!
