Alice hasn't met her traveller father very often, but there's one rule he always impresses upon her: never, ever leave a story unfinished. And for a gifted writer like Alice, that's easy – until she tackles a full-length novel and realises her imagination has dried up. She's a long way into the story before she discovers she has no idea how to finish it. And then she starts seeing shadows out of the corner of her eye, shapes that flit away into the dark as soon as she turns to look at them.
