Nick and Tesla's Secret Agent Gadget Battle

Gr 4–6—With a penchant for inventing and sleuthing, 11-year-old twins Nick and Tesla return for a third mystery. The siblings have been visiting their Uncle Newt, an eccentric scientist, for the summer, while their parents work on a mysterious government project in Uzbekistan. After receiving a cryptic message from their mother warning them of a potential spy, Nick begins to suspect everyone of espionage, while Tesla is not so sure—until the pendant her parents gave her is stolen. The list of possible culprits is lengthy, including Uncle Newt's burly new apprentice, a pair of geriatric maids, a spider-fearing exterminator, and a disgruntled neighbor with an affinity for garden gnomes. Using their ingenuity and science know-how—and a multitude of homemade gadgets—the twins catch the thief and uncover a few more clues about the true nature of their parents' work. Although the third in a series, this entertaining and humorous whodunit is straightforward enough that it can be read as a stand-alone. Cautious Nick and confident Tesla are both well defined, as is the quirky cast of comical characters that surrounds them. As with the previous books, instructions for each of Nick and Tesla's inventions are included, giving resourceful children the opportunity to make their own gadgets. With the promise of more mystery, science, and humor to come, children will be anxiously waiting for more adventures—and more inventions—from Nick and Tesla.—Laura J.
