InterWorld (InterWorld, #1) by Neil Gaiman - ★★★

Cool idea, executed nicely. Reading in the end that it was a TV show idea and was for children explained the quick fashion in which it was carried out, but the idea of a world of Magic and a world of Science and a fractured middle world trying to tie the two together while accounting for the continuious creation of new universes everytime a major decision is made. I guess there's two more... Might be a nice quick read. Thoughtful for children's literature.
