Hero & Villain by Juliann Whicker

In this dark romantic comedy, put away your notions of happily ever after because Daniela Delavigne’s about to rewrite those rules—with an infuriating billionaire tech genius and a mountain of chaos. Also a mountain lion of chaos.

All Daniela wanted was to enjoy life as a fiercely independent heiress with a penchant for corporate take-overs and private cello lesson. Being betrayed by her fiancé, the obvious solution is to run away to Las Vegas to get revenge, seducing the monster, Dirk Dagger, who ruined her life and her business deal. Vegas wasn’t on her five-year plan. But hey, as long as she can get her vengeance on the ground floor, the acrophobic has everything under control.
When a group of vigilantes take over her secret identity, Daniela finds herself swept into an impossibly chaotic existence filled with neon-lit Las Vegas escapades. Worst of all, away from her diabolical family, she starts to think that maybe she’s not cut out for a life of villainy.
Dirk’s on a mission of his own, duking it out with high-tech billionaires and evil family members, all while maintaining that perfect jawline and infuriating charm. He’ll do everything he can to save Daniela whether she wants to be saved or not.
So what’s a girl to do when she’s stuck on a thrill ride with a man who might be her downfall or her destiny? Lean in, of course, especially when the stakes involve dancing on the edge of illicit romance and demolition-worthy fireworks.
