Tracks Through Time (Paperback) (ISBN-13: 9781069719065)

Space is time, and worlds are bubbles on a spiraling track. The system worked fine, until the bubbles started merging, popping, and exploding. Only a kid from the past with a dark secret, a teacher's pet who gave it all up to have fun, a shapeshifting runaway duck, and a magic entity can save the universe. For anyone who's ever wished they had a talking pet rock - we present, Tracks Through Time.
