Novice witch Katie Houseman can talk to animals – but solving murder? That's a spell she hasn't mastered yet. To clear vet Tom Walker’s name, she’s going to need all the help she can get. That includes her familiar, Biscuit, and finally learning how to control her magic. She’s juggling mastering spells – and trying not to break coffee mugs in the process – and trying to solve a case where everyone seems to be a killer. On top of it all, Katie’s also still trying to find her missing great aunt and unravel the clues of her own past. With everything that stands in her way, will Katie be able to prove Tom’s innocence? Or uncover another secret and prove he’s guilty?
