It's easy to believe that Zach's family is magic, and the story doesn't belabor his lack of magic, but rather gives him lots of opportunities to discover what his talents and his objects are. He runs into some predictable trouble, but it's nice to see him work through the process with the help of a good friend.
Zach King is apparently an internet phenomenon, and there is a free app that accompanies this book available at www.zachkingmagic.com. I have to admit that I didn't look at any of the videos or investigate the app, but young readers might find both of these things of interest.
Magic is always an appealing subject to young readers. Fans of King's internet exploits or books like Callaghan's Just Add Magic, Osborne's Magic Treehouse books, Geronimo Stiltoon's illustrated exploits, or older titles like Edward Eager's books will find My Magical Life to be a pleasant diversion.
