Vayda Kimble, a college student in her last semester of school, just found out her plans for graduation are in jeopardy. The perfect rock band she planned to study for her sociology research project unexpectedly canceled their spring tour. Scrambling to find another band that will meet her graduation requirements and limited timeframe, her father suggests Asylum, a hot new heavy-metal band growing in popularity. Without questioning it, she quickly signs up to join their tour. With her plans back on track, she breathes a sigh of relief until she meets the lead singer and his intimidating stare.

Dex Marshall, an angry demon with a broken past, hates Vayda from the moment he sees her, and he isn't afraid to hide his disgust for their new stowaway.

As Vayda climbs the steps of the tour bus, she soon becomes entangled in a hidden world of demons where she is not welcome. As demons plot to harm her, she faces the grim reality where the one demon who can keep her safe hates her.

As Dex and Vayda come to a truce and fight opposition, emotions are heightened. So, when outside forces threaten to tear them apart forever, Vayda finds herself in a desperate battle to fight for her freedom or risk losing her future with Dex completely.
