M.T. Anderson 
Agent Q, or The Smell of Danger! [EPUB ebook] 

In the zany and humorous fourth book of National Book Award winner M.T. Anderson’s Pals in Peril series, Jasper Dash and his friends must escape the clutches of The Awful Autarch!Having mopped up their last crime-fighting caper, our three heroes Lily Gefelty, Katie Mulligan, and Jasper Dash, Boy Technonautare eager to get home. But the secret police in the war-torn realm of fantasy where the three kids are trapped (the state of Delaware) don’t want them going anywhere. Our dynamic trio knows way too much about the whereabouts of certain fabulous treasures to escape the grip of Delaware’s Ministry of Silence. So, chums, it’s a race to the border of New Jersey against spies and government agents and double-crossers…That is, if our heroes make it home alive! Chock-full of ups, downs, twists, turns, a shark pit, and even a band of sentient lobsters fighting on the side of Good, this fourth installment of the Pals in Peril series is every bit as wild, wacky, and wonderfully outrageous as the first three.
