Nick & Tesla's 3 Secret Agent Gadget Battle

In this third installment of the series, 11-year-old whiz-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 is spying on him, and why? To expose the secret agent, Nick and Tesla build all kinds of outrageous contraptions. 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!
