Ellis Weiner’s Templeton Twins series follows brainy fraternal twins John and Abigail Templeton—along with their widowed inventor-professor father and their “ridiculous dog”—as they’re pulled into fast, funny misadventures involving the scheming Dean brothers, who want to steal the Professor’s inventions. Across the two books, the twins rely on logic, wit, and teamwork to outmaneuver sabotage and kidnappings, all delivered in a brisk, joke-heavy style with a conspicuously chatty narrator.
