Arcadian Nights (The Olympians, 3) by Marie Medina
Hermes has been given one task by Aphrodite—keep an eye on Eris at her son’s wedding. The last time the beautiful goddess of discord attended a wedding, the Trojan War was the result. Hermes doesn’t think he has much to worry about until she takes offense at being watched and decides to teach him a lesson with a lust spell in the middle of the reception. Convinced she is not as cold and aloof as she pretends to be, he sets out to seduce her instead, starting them both on an erotic path of discovery that will teach them both lessons they won’t soon forget.
