Fourth grade Krystal is a psychic but only her friends, Claire and Billy, know of her ability.  After a collision with Billy, Krystal discovers she can now also hear what animals are saying!  The chapters are short and the sentences are simple.  This book is the 4th in the series but they do not need to be read in order.  Although Krystal is in the fourth grade, this book will be more enjoyed by younger readers.  Illustrations are cartoon-like in black and white.  In the back are horoscopes and instructions for making a paper fortune-teller.  Included is a website containing videos, contests, games, and puzzles.
