"In a world where demons hide amongst humans, some good, some deadly, the immortal Protectors defend the innocent against those that mean them harm, while finding themselves defenseless against the powerful force of love." Things are not at all what they seem in Atlanta. When the sun falls, the "others" rise. Emma Blake, a half-demon, risks everything including her life when she approaches a powerful immortal slayer to help rescue her sister from a vindictive master demon. When Cynden (Cyn) Fraser agrees to assist the intriguing Emma, he never expects to be pulled into a territory so wrought with treachery that neither of them may survive.
