Into The Sideways World (Pb)

When twelve-year-olds Willa and Manny hear of a mysterious animal prowling their town, they are determined to prove it is real. Following the creature into a cave one full moon, they are swept into an alternate, ideal, world ? one where pollution and
conflict have been conquered decades ago and even their own families seem happier.
But when they return, no one believes them. So, with a global war looming in their own world, their quest for proof of the Sideways World becomes ever-more urgent, in a nail-biting race against time.
