Ana relocates to the United Kingdom to pursue her studies at a prestigious university alongside her closest friend, unaware that fate has orchestrated an encounter with an ancient tome. This mysterious book harbors the power to invoke the Prince of Darkness himself—a dangerous artifact that falls into Ana's possession against her will. Now entangled in a contract with a force beyond mortal comprehension, Ana must navigate treacherous secrets, supernatural threats, and an inescapable bond with the dark prince. As her life spirals into peril, she discovers that some bargains exact prices far higher than the initial cost, and the line between salvation and damnation becomes increasingly blurred.
