Purchase this book on Amazon here! The Wizards of Once is the latest middle grade novel by Cressida Cowell, the author of the How to Train Your Dragon series. Wizards and warriors have always been taught to hate each other. The wizards stay in the forbidden Badwoods and the warriors live in their iron castle. But when Xar, a wizard, and Wish, the warrior queen's daughter, meet each other in the woods, they find that they must work together to fight the one thing everyone is afraid of: witches. Sex: None. Language: None. Xar uses his own cursing. Drug/Alcohol Use: None. Violence/Gore/Frightening Scenes/Death: There are a few suspenseful scenes and battles, but nothing too over the top. Final Note: This book was cute, but it wasn't my favorite. It would be a good stepping stone for younger readers who are showing an interest in things like Harry Potter , but who aren't quite old or mature enough for that particular series.
