What's the Story?

MAC UNDERCOVER: MAC B., KID SPY, BOOK 1 tells the "true" story of author Mac Barnett, who claims that, as a kid growing up in California, he got a call from the Queen enlisting his help recovering some stolen Crown Jewels. When Mac flies to London to investigate, he follows the trail of the missing Coronation Spoon to Paris, where he gets caught up in another theft at the Louvre Museum. The plot thickens when he ends up in Moscow, negotiating with a slippery KGB agent. Will Mac recover the jeweled spoon and the famous art as well? And what could the thief possibly want in return?

You don't get much more kid friendly than this rollicking, illustrated spy adventure. Mac Undercover: Mac B., Kid Spy, Book 1 is pure fun to read, as the dry-witted kid narrator is whisked off to England, France, Russia, and home again, all in service to the Queen of England. Author Mac Barnett has a reputation as a sly and witty prankster, and kids will love his insistence that this fantastic story "actually happened to me." A Top Secret note opens the book, claiming, "I was a spy for the Queen of England when I was a kid. It was a different time. 1989, to be exact."

The jokes are equally divided between the text, with its fast-paced silliness, and cartoon-like illustrations by Mike Lowery. There's art on most pages, and it delivers some of the punch lines; for instance, throwing shade on British cookies by labeling a dry-looking biscuit both "Dog Biscuit (USA)" and "Biscuit (England)." Seamlessly woven into the fun is some solid nonfiction content -- including historical notes about the countries Mac visits.
