A plague threatens his kingdom but one kiss could rule his heart... Kassandra grew up with myths of Titans and Sirens thanks to her father, but never did she imagine one of these mythological creatures would pop out of an ancient book she discovered in the library. Darius is unlike any man she's known. He's commanding but loyal to his family and he shows her a secret power she never knew she possessed. When he claims to need her help, Kassandra vows to use her special talents to help. Darius is a Titan of the sea, trapped inside a book for a decade when he left his home on a mission to save his world. He's on a deadly time crunch and fears the plague, which had been destroying his undersea kingdom has spread in his absence, and is forced to bring along Kassandra, knowing it could very well put her life in jeopardy. Forced to find magic relics that could end the plague, Darius comes face-to-face with the decision of a lifetime. Let Kassandra drown or give her the kiss of life which will turn her into a Siren and bound her to him for eternity. But one kiss can't change the woman. Darius must learn to trust in Kassandra's abilities if he's going to find a cure for his undersea kingdom, all the while trying to avoid being captured and leading them both into a fate worse than death.
