In a perfect world there'd be no need for Animal Magic Rescue Centre. But Eva and Karl Harrison, who live at the centre with their parents, know that life isn't perfect. Every day there's a new arrival in need of their help. Fern is the softest, prettiest cinnamon-coloured rabbit imaginable, and her young owner, Mia, is completely devoted to her. When Fern falls ill, Mia brings her into Animal Magic but, despite Heidi and Jen's expert care, Fern just gets sicker. Will Eva and the team be able to figure out what's wrong with the gorgeous bunny before it's too late?
