Desperate to stop her beloved from marrying another, sixteen-year-old Evangeline Fox strikes a deal with the mythic Prince of Hearts leading her down a dangerous path that may ultimately end in her destruction. Raised in her father's curiosity shop, Evangeline Fox grew up on legends about immortals, like the tragic Prince of Hearts. She knows his powers are mythic, his kiss is worth dying for, and that bargains with him rarely end well. When Evangeline learns that the love of her life is about to marry another, she becomes desperate enough to offer the Prince of Hearts whatever he wants in exchange for his help to stop the wedding. The prince asks for three kisses. After Evangeline's first promised kiss, she learns that the Prince of Hearts wants far more from her than she's pledged. He has plans for Evangeline that will either end in the greatest happily ever after... or the most exquisite tragedy. -- adapted from Goodreads info
