There's so much to love about October - Halloween, pumpkin everything and MAGIC. Especially magic. But for nervous young witch Clemmie, this October might see the stars descend on her for the first time, bringing with them a whole month of chaotic new power.

She's spent twelve years watching her mum, aunts and cousin receive their October power and knows that, for the Merlyns, magic can get very messy. And there are those who want to harness their magic and make it last beyond October. It's a bold experiment, until Clemmie and her coven find themselves in mortal danger.

What price must be paid for magic that never ends? Or for having magic at all?
