A young pickpocket gets recruited into an elite group of thieves in this “page-turning, edge-of-the-seat” (Publishers Weekly, starred review) upper middle grade boarding school adventure full of heists, danger, and secret plots perfect for fans of Spy School and Keeper of the Lost Cities.

Tom Morgan’s life on the streets of London consists of shining shoes, picking pockets, and keeping his group of street kids out of the hands of snatchers. When he fails at the last and their home is raided, Tom is the only one not carted off to the workhouse. He’s determined to rescue his friends, but breaking into the workhouse is a nearly impossible task, let alone breaking back out.

Tom is at a loss until he’s approached by a mysterious figure claiming to be an accomplished thief and Tom’s ticket to the best training in the clandestine arts in the world: an elite international boarding school that would teach him all the skills necessary to help his friends. Without any better ideas—and his curiosity piqued—Tom accepts the invitation.

Whisked away to the snowy Alps, Tom enters a thrilling world of intrigue and heists. But the deeper he gets into the Shadow League, the harder it becomes to leave. Tom has to learn fast and uncover the nefarious secrets within the league to have any chance of saving himself, his friends—and maybe even the world.
