Kid inventor Lexie Moon has built a scrap-box remote-control car she hopes will win second prize in the local competition—a Mega-Boost signal amplifier she desperately wants. But when her transmitter and the prize disappear, Lexie discovers they’ve been stolen by Connie van Quish, sister of the infamous Gizmo Lightfinger. Connie has combined them into a powerful UniMote, a device capable of controlling any remotely operated machine. With gadgets across town spiralling into chaos, Lexie and Grandad race to track down the UniMote, stop Connie’s schemes and restore order. Along the way, Lexie discovers that teamwork, family—and even little sisters—can make all the difference. A fast, funny STEM-themed adventure filled with invention, problem-solving and remote-control mayhem.
