Nick and Tesla's Secret Agent Gadget Battle

On the heels of NICK AND TESLA'S HIGH-VOLTAGE DANGER LAB and NICK AND TESLA'S ROBOT ARMY RAMPAGE, here comes a third book of middle-grade adventures (and top-secret contraptions!) In this third installment, 11-year-old wiz-kids Nick and Tesla discover that someone in the quiet town of Half Moon Bay has placed their beloved Uncle Newt under electronic surveillance--but who's spying on him, and why? To expose the secret agent, Nick and Tesla will build all kinds of outrageous contraptions, including door alarms, spy gadgets, a secret book vault, and more. Throughout the book, the narrative is interrupted by blueprints and instructions so that budding young inventors can follow along. Science and electronics have never been so much fun!
