Electric Idol (Dark Olympus #2)

In the ultra-modern city of Olympus, there's always a price to pay. Psyche knew she'd have to face Aphrodite's ire eventually, but she never expected her literal heart to be at stake...or for Aphrodite's gorgeous son to be the one ordered to strike the killing blow.

Electric Idol is book number 2 in the Dark Olympus series by Katee Robert.
