Barnett recalls another exploit from his childhood days as a secret agent for the queen of England.Shortly after failing to convince the despicable Craig, his mom's boyfriend, that the wrestling at WrestleFest Live is (spoiler alert) faked, young Mac receives a call from the worried monarch. It seems that the Tower of London's ravens are being stolen, and as everyone has heard the old prophecy that if the ravens ever go so will the country, there will be general pandemonium when the news gets out. "Who cares whether the prophecy is real," the psychologically astute royal cogently remarks. "The prophecy is true." Following a trail of convenient clues—and learning along the way (this is likewise true) that the queen legally owns every British mute swan, sturgeon, dolphin, and porpoise—Mac travels to Iceland and then the North Pole, catches up with the "KGB Man" who did the dastardly deed, and scotches a scheme to kick-start the prophecy with a public TV announcement. He accomplishes this by ripping off his shirt and wrestling the thief on camera…thus indelibly remaking a real news story into the fake sort. Lowery shovels in further goofy notes with three-color cartoon drawings of various animals and the white-default human cast on nearly every page.Exciting action sneakily infused with points about the relationship between reality and story, delivered by a narrator who can claim with literal truth that he saved the day "on porpoise." (Spy thriller. 7-10)

Gr 2-5 Mac, kid spy international, is back! On special assignment from the Queen of England herself, Mac drops everything back in the United States to assist in a missing raven caper in which the Russians may be involved. This short chapter book, with a familiar graphic style from previous volumes, does not disappoint. Mac travels all the way to Iceland to track down spies and the Queen's beloved corgis somehow get entangled in the adventures as well. Silly high jinks ensue as Mac saves the day in this third installment. VERDICT Highly recommended for fans of the series, this title features more of the wacky humor they have come to expect.
