Life has not been easy for Thomas since his dad died. His mother is acting strangely, he needs to care for his younger sister and things at school aren't great. And then there's the Other Shadow. The shadow that doesn't belong to anyone. The shadow that wants to be Thomas' friend. But who can you really trust when your world is falling apart?

WARNING: This story contains magic, witches, talking animals (well, at least one), potato charms and a huge amount of fun! Cooper is not the beautiful, golden guinea pig of Jinny's dreams. He's trouble! Not only can he speak and read, he can disappear, hover in the air and teleport small distances. He's obsessed with junk food and full of tall tales, but worse still, Cooper is convinced that Jinny's kindly, elderly teacher, Miss Bunney is a witch. Come on, Cooper, really?

When Jinny and her brother, Tyrone, find a ring in Miss Morgan's attic, they have no idea about the danger they're in. Tyrone awakens a genie, and once he's made one sneaky little wish, he can't stop! Can Jinny and Cooper save Tyrone before the genie's curse traps him forever? And can Cooper resist using the ring to wish for a cake as big as a house? Don't do it, Cooper!
