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…

Winner of the 2018 Edgar Award, VANISHED brings back Florian and Margaret as covert consultants for the FBI's hush hush Special Projects team. In this case, a young cellist disappears during intermission at the Kennedy Center and the heroes follow the mystery all the way to the White House. In its starred-review, Kirkus Reviews called it "A splendid whodunit: cerebral, exhilarating, low in violence, methodical in construction and occasionally hilarious."


Florian and BFF Margaret are back for their third adventure as they try to uncover a spy ring and clear the good name of Marcus, their friend and FBI handler, in a mystery that Kirkus Reviews calls "A top-shelf test of courage, friendship, and ingenuity." Along the way they try to evade a suspicious FBI agent, decipher a secret code that has been used for years to pass secrets in the open and escape from a vault underneath the Library of Congress.

"An action-packed plot to breathe new life into the zombie genre."
