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. Isla, her beautiful unicorn, Buttercup, and their friends are determined to find the person responsible for draining the island's magic and stop them! But Valentina is behaving very oddly, and it's not just because the head of the academy is her aunt. Does she know something about Ms Willow that the others don't?
