Big Demon Energy: An Enemies-to-Lovers Urban Fantasy. Bedeviled AF, #1

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. If it wasn't enough that he broke her heart six years ago, he's returned with an infuriating talent for getting under her skin. Avi would love to stake him and call it pest control-but she needs this promotion a hell of a lot more. However, when a killer sets their sights on her team, playing by the rules won't be enough.
Now she has to decide: toe the line-or unleash her full power and show everyone what she's made of. If you love Chloe Neill's Chicagoland Vampires, Big Demon Energy delivers a smart, determined heroine, a banter-fueled vampire romance, and high-stakes supernatural intrigue.
