Praise for SWITCH

This book has helped my son, 5, move on from picture books at bed time to one with more words. An excellent choice for reluctant readers who will be thrilled at the idea of turning into a bug, mad inventors and lots of adventures.

The book is great fun and involves the reader, who really feels as though they are part of the story. Along the way the reader learns a surprising amount about pond life.
