Whatever her name is, it won’t last long. Katrina doesn’t know any of the details about her past, but she does know that she and her parents are part of the Witness Protection Program.

City Spies
Published: March 10, 2020
Sara Martinez is a hacker. She recently broke into the New York City foster care system to expose her foster parents as cheats and lawbreakers. However, instead of being hailed as a hero, Sara finds herself facing years in a juvenile detention facility and banned from using computers for the same stretch of time. Enter Mother, a British spy who not only gets Sara released from jail but also offers her a chance to make a home for herself within a secret MI6 agency.
Operating out of a base in Scotland, the City Spies are five kids from various parts of the world. When they’re not attending the local boarding school, they’re honing their unique skills, such as sleight of hand, breaking and entering, observation, and explosives. All of these allow them to go places in the world of espionage where adults can’t.
Before she knows what she’s doing, Sara is heading 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…

Published: July 14, 2015
Everyone in twelve-year-old Hale’s family is a spy, going way back. They’ve all worked for the Sub Rosa Society, an elite organization that’s so top secret that new agents aren’t recruited; they’re born. Despite the fact that Hale can defuse an explosive, don a disguise in seconds, and speak eleven languages, Hale isn’t like his spy-school classmates– he is, as his mother puts it, “big-boned,” and as everyone else puts it, “fat.”
But when Hale’s parents go missing while on a secret mission–likely captured by SRS’s number one enemy–it’s Hale’s time to step up and (with a little help from his acrobat cheerleader little sister) save the day. The trouble is, when you’re surrounded by spies, who can you trust?
