From award-winning Richard Byrne, author and illustrator of This Book Just Ate My Dog, (shortlisted for the Children's Book Award) comes another brilliantly inventive book starring Ben and Bella.
When Ben is tempting his cat across the page with a fluffy mouse, his cat . . . disappears! Then his best friend Bella disappears, too. Sniffer dogs and rescue teams can't help . . . When Ben also vanishes, there's only one person left to help. You, the reader! Can you release Ben, Bella, and the cat from the mischievous book? It's a ticklish problem.
Original, simple, and witty, this high-concept picture book plays with the physical attributes of a book to create a real page-turner.
