Jane’s birthday becomes the day everything falls apart. Her fiancé Adrian abandons her in a hunter's pit and watches without pity, all to protect another woman. Rejected by her family and betrayed by the man she trusted most, Jane chooses the only bargain left to her: a deal with the devil. Seven days later, the world waits for her to grovel for Adrian. Instead, she answers with a smile and hands him to her rival. Because within seven days, another wedding will take place—and this time, the bride will not be claimed by any man, but by a devil. By the time Adrian understands what he lost, it will be too late.
