Sara Martinez is a hacker facing years in juvenile detention, until she meets Mother, a spy who gets her out of jail and into MI6, British Secret Intelligence.

Operating out of a castle in Scotland, the City Spies are five kids from around the world who've fallen through the cracks only to form a family like no other. When they’re not at the local boarding school, they’re mastering spy skills like sleight of hand, breaking and entering, covert observation, and explosives. So they can go places in the world of espionage where adults can’t.

Before she knows what she’s doing, Sara's off to Paris for an international youth summit, hacking into a rival school’s computer to prevent them from winning a million euros, dangling thirty feet off the side of a building, and trying to stop a villain…all while navigating the complex dynamics of her new team.

No one said saving the world was easy…

After taking down a mole within their organization, the City Spies are ready for their next mission—once again using their unique skills and ability to infiltrate places adults can’t. The sinister Umbra has their sights set on recruiting a North Korean nuclear physicist by any means necessary, and the City Spies plan to keep an eye on his son by sending Paris to the chess prodigy’s tournaments in Moscow and Beijing.

Meanwhile, Sydney’s embedded as a junior reporter for a teen lifestyle site as she follows the daughter of a British billionaire on tour with the biggest act on her father’s music label to uncover what links both the band and the billionaire have to a recent threat from an old Soviet missile base.

From a daring break-in at one of London’s most exclusive homes to a dangerous undercover mission to a desperate search and rescue operation on the streets of Beijing, the City Spies have their work cut out for them on their most dangerous mission yet.
