Sam Swallow and the Riddleworld League
All Sam Swallow wants is to join the Little League baseball team. But on the way to the park he stumbles, hits his head and falls into Riddleworld, a land where birds talk in puzzles and cats wait to pounce. Nothing is what it seems to be in Riddleworld. Sam himself has been transformed into a bird. To get back to this world, Sam needs to solve some difficult puzzles, make a few unlikely friends and avoid the cats at all costs.
