The Lucky Black C.A.T. — Andrea Eames

“There's no time for all this,” said the cat. He cleared his throat dramatically. “I come from the Lost Land. No, don't interrupt yet, I'll explain. It's a place where everything lost from this world goes. Unicorns, dragons, spare change, socks … You know how you always lose one in the washing machine? It goes to the Lost Land.” A perfectly ordinary summer turns into a wild adventure, when Duncan and Emma meet a talking cat who takes them to a magical other world, under attack by werewolves, and they find out that they might be the only ones with the power to save it.
