A New York Times bestseller!

Soar into a breathtaking world of heroes and unicorns as you’ve never seen them before in this “unexpected, suspenseful, and heartwarming” (Kirkus Reviews) middle grade debut perfect for fans of the Percy Jackson and Eragon series!

Skandar Smith has always yearned to leave the Mainland and escape to the secretive Island, where wild unicorns roam free. He’s spent years studying for his Hatchery exam, the annual test that selects a handful of Mainlander thirteen-year-olds to train to become unicorn riders. But on the day of Skandar’s exam, things go horribly wrong, and his hopes are shattered…until a mysterious figure knocks on his door at midnight, bearing a message: the Island is in peril and Skandar must answer its call.
