Hot & cold, by Susannah McFarlane
This is the first book in the EJ12 series and possibly the best. In this book EJ has to save the polar ice caps from melting!!!! Can she stop Doctor C.hill in time to save the penguins?!
General: I recommend this book for people who like adventure, animals and Secret Agents!
