Fool Me Twice by Ellie Roth

“She’s my situationship. My significant bother. The bane of my existence.”
“Those sound like pet names to me.”

Roma Gutierrez, demon hunter, has been given an impossible assignment: regain the trust of her former friend, rogue hunter JJ, and bring him back to the Sanctum. With her reputation—and her future—on the line, she devises a false flag operation to get close to him and his new demon buddies… but when a spell goes wrong and the fake conflict turns real, she’s forced to rely on a famed demon spellcaster to fix it.
Esmeralda Laguerre, demon, doesn’t trust Roma as far as she can throw her—especially since Roma already tricked Ez’s friends once before. But with dangerous interdimensional rifts opening at random throughout Redwater, only a combination of demon magic and human magic can close them… and Roma’s spellcasting prowess unfortunately makes her Ez’s only option for help.
As their alliance deepens, Roma and Ez slowly discover that their clear-cut sides aren’t as clear-cut as they’d like to think. But while Ez’s trust in Roma grows, so does Roma’s guilt about her mission—and her role in manufacturing their current crisis. With the fate of their hometown on the line, will they be torn apart by secrets or come together to protect everything they hold dear?
