Fourteen-year-old Aria Loveridge lives at the Resthaven Home for Dreamslingers, a safe haven for children born with a genetic mutation that transports them to a powerfully magical realm while they sleep. But this magic can be unpredictable--even deadly. After all, it was only ten years ago when members of the Royal League of Dreamslingers caused the Great Outburst--a tragedy that killed hundreds of people, including Aria's mom.

Since then, Aria's dad has become leading expert on Dreamslinger Welfare, which means Aria knows better than most what it takes to keep society safe from her, and others like her: separation, identification, and most importantly, power suppression.

So when the Kingdom of Royal Hanguk--home of the Dreamslinger League--announces the first Dreamslinger trials where teenage slingers from around the world are invited to compete for a chance to join the League and learn how to use their powers, Aria knows what she must do: join the trials and take down the League from the inside.

But the Trials introduce Aria to a world of wonderous magic and friendship, a world where she finally feels like she belongs. And as dark secrets from the past are revealed--ones that make Aria question her very identity--she becomes even more determined to discover the truth for herself. She just has to survive the trials first.
