On what should be a routine mission to stop a hack at a tech company, young spies Caleb Swift and Zen Rafiq--code names Swift and Hawk--discover out-of-control weaponized robots threatening to escape into the street. With help from Caleb's AI companion, Sam, they avoid catastrophe. But this isn't a one-time incident: a dangerous organization is behind the attack, and now they're plotting something even more sinister. Fortunately, Zen is the perfect candidate to infiltrate the group. Caleb thinks it's too dangerous, but who else can climb, fight, and build microbots as well as Zen? Plus, she'll have Caleb's incredible tech skills behind her, not to mention the support of the ARC Institute's elite Möbius Program. Going undercover is a big risk, but with lives on the line, it's one Swift and Hawk will have to take. Packed with high-octane chases, epic cyber-battles, and the latest gadgets, the second adventure in this exciting series is an edge-of-your-seat thrill ride.
