An addictive new spy adventure series for Alex Rider fans who love action-packed stories and all things tech. When their families mysteriously disappear, Swift and Hawk, teen experts in AI and robotics, are recruited by the secretive Mobius Program to crack an unbreakable code. They are immediately plunged into a life-and-death rescue mission, that takes them from hidden tunnels beneath the British Museum, to the dangerous docklands of Amsterdam in search of the mysterious ship The Nightfall. Caught in a treacherous world of spies and saboteurs, Swift and Hawk will be pushed to the limit as they follow a trail that leads to the remote island of Spoklestark, and straight into the hands of a dark and chilling enemy.

In the second book of this action-packed series, cutting-edge tech meets explosive adventure as young superspies Swift and Hawk take on a dangerous secret organization. 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.
