Raves for the Raven Who is a Therapist This book grabs you from the outset and takes you on a hopeful journey: A colorful, spunky raven (with a Ph.D.) travels to Australia to meet a quokka who has lost his true smile, finds it hard to move and isn't hanging out with friends anymore. Dr. G knows that depression is the culprit, and extends a listening ear and helping hand, all the while reassuring the quokka that lots of adults and kids feel depression, too!
