Petty thief Malinda Castan cares about one thing: saving enough money to leave the Nightingale, a house of cutpurses and unsavory characters, so that she can have a normal life. She lives under one rule: reciprocity - a life for a life, favor for favor. So, when the Prince of Darkness saves her from being killed, and offers her one last job, “To steal a mask that will pay more than she could earn in a lifetime"... Malinda says yes not only for the money, but because she owes him. To steal the mask, she will pose as his betrothed, even while suspecting him of lying about his motivations and his past. To save her own life, Malinda will master dark magic and make deals with multiple Gods. And to save him, she will stake her most precious possession: her heart.--
