For fans of Cassandra Clare, this kick-ass new series will keep you on the edge of your seat . . .

With an occult detective for a dad, Diana's normal life has never been too normal. Uprooted by investigations, she finds herself on a long train journey to Edinburgh, sitting next to a boy who makes her heart melt. Or something melt. Anyway, she's melting. Maybe a new life in Scotland won't be so bad after all.

But when Di's recurring nightmares start to come true, her destiny changes for ever. After her dad goes missing, she becomes part of a Trinity of Demon Hunters. Along with her two new friends, she needs to face down death, rescue her dad and save their city. Because that's what Demon Hunters do, right?

There's only one question left to answer: how do you kill a dead man?
