Imagine a school where you meet your own unicorn and have amazing adventures together! That's what happens for the girls at Unicorn Academy on beautiful Unicorn Island.

Lily is thrilled to be joining Unicorn Academy, and she's relieved to be paired with a unicorn who seems to be as shy as she is. They immediately become fast friends and are welcomed into Amethyst dorm. But then they learn that Unicorn Island is being threatened by destructive purple tornadoes.

Will Unicorn Academy survive and can Lily and Bramble do anything to help save it?
