Greek myths get unspeakably hot new twists in this contemporary series from New York Times and USA Today bestselling author Katee Robert. Apollo's official title is Keeper of the Lore, but the truth is that he deals in more secrets than anyone. And now that a new enemy has taken up residence in Olympus, Zeus turns to Apollo to find answers. But even his extensive skills bring up nothing about their enemy...Which means it's time to pull out the big guns. Cassandra Gataki is a member of a fallen house, and no one in Olympus's glittering upper city lets her forget it. With her parents in exile, it's up to her to provide for her younger sibling. She's forever skating the edge of power while fighting not to get too close, lest she make the same mistakes her parents did. When her boss, Apollo, comes to her with an invitation to accompany him to a week-long house party hosted by the new power player in Olympus, Cassandra turns him down flat. Apollo might take no for an answer, but Zeus won't. He commands Apollo and Cassandra to find answers, no matter what it takes — even if it means going 'undercover', attending the house party as a couple in order to get Cassandra access to places the more infamous Apollo can't reach. As the week progresses, real sparks fly in their fake relationship. But if their host finds out their true purpose, the least of Cassandra's worries will be a broken heart...
