When Connie is sent to live with her aunt, she knows it's going to be one more place where she doesn't fit in. But soon she realises how wrong she is. The seaside town is full of adults and children who have strange links to creatures. It's the heart of the secret Society for the Protection of Mythical Creatures, a group of people sworn to ensure that mythical beasts are kept safe. Normally the creatures and their chosen humans work in harmony. But something abnormal is happening here. The Sirens, who for generations have kept their deadly song to themselves, are once again luring humans to their deaths. It doesn't take long for Connie to realise that the victims are oil workers. The Sirens are fed-up with their seas being polluted, but should the Society protect the Sirens or the oil industry? Connie doesn't think she has a role to play, until it becomes clear that she's a Universal - the first person in over a century who can communicate with every type of beast on earth and in the air. Her power is immense. It corrupted the previous Universal...and now he's back. And he'll use any means he can - from violence to the terrifying Storm Giants - to turn Connie to the dark side.
