Sixteen-year-old Cyrus Hampstead competes in the thrilling, spark-flying arena of combat robotics, where mechanized obliteration is the name of the game. Armed with the prized bot he built with his late father, Cyrus is determined to claim victory at ComBot, the ultimate competition in robotic warfare. But when he faces off against the legend of the sport, a megalomaniac with a win-at-all-cost mentality, his dream becomes a charred ruin. Suspecting foul play in his defeat, Cyrus must face a daunting truth: he's lost not only his prized bot but also the guidance of his father. Struggling to build his robot and confidence, Cyrus gets a glimmer of hope from unexpected sources-a surprising discovery and a partnership with the savvy and confident Leslie. As the new ComBot season looms, Cyrus battles a shoestring budget, budding feelings for Leslie, and a temperamental robot with a mind of its own. Can he find redemption in the "decagon," or will a long-held secret bring his headstrong quest to a screeching halt?
