Javan Najafai, the crown prince of Akram, has spent the last ten years at school, far away from his kingdom. He’s been eagerly awaiting his return home to his ailing father, but his journey there goes dangerously wrong. A mysterious imposter has taken his place—and no one will believe Javan is the true prince. After barely escaping the imposter’s hitmen, Javan is thrown in the most dangerous prison in his kingdom—Maqbara. The only way to gain an audience with the king and reveal the truth is to fight his way out in the prison’s yearly tournament, which pits inmates against a coterie of the deadliest creatures in the world. The one person who can help him is Sajda, a strong and secretive girl who has been enslaved by Maqbara’s warden since she was a child. Working with Sajda might be the only way Javan can escape alive—but she’s hiding something. Together, Javan and Sajda will have to outwit the dangerous warden, outfight the hundreds of deadly creatures, and outlast the murderous prisoners intent on killing Javan before he can win—in order to fight for their freedom, and take down the imposter once and for all.
