Query: A very charming, engaging story

This cast of feline characters is simply wonderful. Don't think of it as a book just for children, it's overwhelmingly entertaining for adults as well. Tad Williams, in his special unique way, made his characters-- CATS! They speak, behave, and accomplish their goals as any cat would, not furry fuzballs with human attributes. Humans don't belong in this action filled quest to solve a mystery of a missing girl kitty that, our hero, a male cat, is desperate to find. It's a love story as well as a difficult dangerous mission. Can he find her? His gut wrenches with fear of what he might find if he succeeds. Trust me, it's a can't put down book.
