In this eighth installment in the New York Times bestselling series from Edgar Award winner James Ponti, the spies head to the land down under as they race to stop a nefarious cybercriminal from wreaking havoc.

London’s not sure she made the right choice in joining the City Spies, but she doesn’t have time to reconsider as the team plunges into a mission that races from the ski slopes of Norway to Australia’s Great Barrier Reef. They’ve been tasked with safeguarding a game-changing piece of high-tech hardware being developed by Britain’s top secret ARIA program. If it falls into the wrong hands, the consequences would be dire. But to protect it, the team has to outwit an unexpected team of rivals.

For the City Spies, this means trying to win a game without knowing all the players. For London, it requires putting aside her doubts and acting like a spy so she can figure out who she can trust and who is the enemy.
