Darkly By Marisha Pessl

A seemingly ordinary high school student. A mysterious summer internship. And a legendary games designer, now dead.

When an ad for an internship with the Louisiana Veda Foundation appears, Arcadia 'Dia' Gannon rushes to apply. Veda's game-making empire, Darkly, was renowned for its ingenious and terrifying games back in the day and Dia is as obsessed with them as anyone.

The remaining games are priced like highly sought-after works of art, with the rarest and most notorious commanding tens of millions of dollars at auction. Now, Dia is thrust into the enigmatic heart of the operation. But who are these other interns? Why do they all seem to have something to hide? And why was she really chosen? It soon becomes clear that this summer will be the most twisted Darkly game of all.
