Arcadia “Dia” Gannon is obsessed with Louisiana Veda, the game designer whose creations and company, Darkly, have gained a cult-like following. Dia is shocked when she’s chosen for a highly coveted internship, along with six other teenagers from around the world. Darkly, once a game-making empire renowned for its ingenious and terrifying toys and games, now lies dormant after Veda’s mysterious death. The remaining games are priced like rare works of art, with some fetching millions of dollars at auction.

As Dia and her fellow interns delve into the heart of Darkly, they discover hidden symbols, buried clues, and a web of intrigue. Who are these other teens, and what secrets do they keep? Why were any of them really chosen? The answers lie within the twisted labyrinth of Darkly.
