If You Ride A Crooked Trolley . . . (Otherwise)

One winter morning, a young boy rides a mysterious yellow trolley to Otherwise, where things that didn't happen in the "real" world, but might have, actually occur. In his first adventure, the boy lands in the middle of a war over a lost magic spell that might end the existence of both Otherwise and the "real" world. He and a brave young girl he meets rediscover the magic spell and save their worlds from destruction.
