The truth lies with only those willing to seek it. Elena, daughter of the God of War, has known nothing but training to lead the Gods' armies all of her life. Determined to let nothing get in the way of that goal, she is selected to complete a task for The Twelve, or the Olympians as the mortals call them. Her task? Retrieve Persephone from the Underworld. Ready to watch the Underworld burn, she arrives in Hades' Court, immediately thrown in with The Children of the Night-a dangerous group of siblings said to take pride in killing mortals, especially their leader, Thanatos. Forced to work together over her stay, Thanatos finds himself unable to deny there is something that draws him to Elena, and Elena to him. But he will stop at nothing to protect his family and to ensure Alina fails the task that brought her to the Underworld. Forced to decide between duty and desire, the state of the Underworld hangs in the balance. The cost of this choice could be deadly.
