Big Demon Energy: An Enemies-to-Lovers Urban Fantasy (Bedeviled) by Deborah Wilde

She’s just a demon, standing in front of a vampire, trying not to punch him. Aviva Fleischer is climbing the ranks in supernatural law enforcement—one arrest at a time. Determined, quick-thinking, and hiding a not-so-little infernal secret, she's worked hard for her promotion. Too bad it comes with strings attached: partner with a covert agent, investigate a bizarre string of murders, and try not to set anything on fire. One problem. Her new partner is Ezra Cardoso. He’s a wildcard vampire with charm for days, the ruthlessness to match, and—worst of all—her ex.
