“Cooper and the
Enchanted Metal
Detector”
Adam Osterweil
Namelos Books, $18.95
Goodbye school, hello summer reading. “Cooper and the Enchanted Metal Detector” is a novel for middle-grade readers that takes place over the course of a pivotal summer for Cooper, the 10 (or perhaps 11)-year-old protagonist. A complete epoch can occur bookended by June and August, and Adam Osterweil, who has brought young readers “The Comic Book Kid” and “The Amulet of Komondor,” among others, seems to know all about the arc of summer.
