**Summary:**
Mariana Rivera is a devout Christian and a straight-A student entering her junior year of high school. She lives a quiet life in a small town, balancing her studies, church activities, and a part-time job at a local bookstore. Her life is simple and predictable-until she meets someone who changes everything.
One day, a new student named Lucian transfers to her school. Mysterious and charming, he instantly catches the attention of everyone, but he seems particularly interested in Mariana. Unbeknownst to her, Lucian is not just a new student-he's a demon in disguise, sent to collect souls for the devil.
During a chance encounter at the bookstore, Lucian convinces Mariana to make a wish, promising that he can make it come true. Desperate to help her struggling family, she makes a deal, unaware of the true cost. The deal binds her to a demon named Azazel, who takes the form of a boy her age. Unlike Lucian, Azazel isn't there to harm her; he's intrigued by her faith and purity.
As Mariana struggles with the consequences of her deal, Azazel becomes her secret guardian and, eventually, her secret boyfriend. The two form a forbidden bond, navigating the dangers of their opposing worlds. Mariana must hide her relationship from her devout family and friends while trying to find a way to free herself from the contract.
But as the lines between love and sin blur, Mariana finds herself questioning her beliefs and the nature of good and evil. Can love truly exist between a human and a demon? And will Mariana find a way to escape the deal without losing her soul-or her heart?
