Dreamless

A story of love, destiny and feuding families with extraordinary powers, descended from the heroes of ancient Greece, Dreamless is the second book in the heartstopping Starcrossed series by Josephine Angelini.

Distraught, Helen meets another person down in the shadowy underworld: Orion, descended from Adonis and with the power to control desire, he is the heir to the house of Rome. He's also kind of hot.
