Bad blood - Rhiannon Lassiter

In an abandoned house in the Lake District, a cupboard door opens into a playroom. Buried in dust is a collection of children's books in which the names of characters have been savagely crossed out.Here three children played a make believe game, sacrificing their dreams and wishes to make what they believed come true. But the game was never finished and in the woods behind the house something waits, hungry for the only food it knows.Now a new family has come to the house. Soon they will discover themselves in the game. But they do not know the rules. And they are the pawns, not the players . . . Thrilling, chilling, and completely gripping.
