A dead body is never a welcome sight, but it’s especially troublesome when Tadd Leventis and Declan Anagnos return home to find one in their foyer. Most people know the dead woman as a curator at the local museum, but Tadd and Declan recognize her as someone from their distant past—Athena, the Greek goddess of wisdom and strategic warfare. To Tadd and Declan, it's more than a murder. It's a threat to the mortal lives they've worked so hard to build—and a wakeup call that their immortal lives are in danger too.
At Zeus’s request, they once again don the mantles of Ares and Hermes, but when they start investigating their fellow Olympians, Tadd and Declan discover things are far more complicated than they seem. As the body count rises, tracking the killer becomes more dangerous, and the investigation starts to strain their relationship. Can they patch things up in time to catch the killer, or will the killer catch them first?
