Variable Onset by Layla Reyne

Special Agent Lincoln Monroe never breaks rules. Especially the one that says Carter Warren, his former student turned cocky field agent, is off-limits.

Except they’re undercover as newlyweds in a quirky small town where everyone is watching, everyone is talking, and their fake marriage is supposed to look real. It’s not supposed to feel real.
For Carter, it’s everything he never stopped wanting and nothing he can survive with his self-control intact. Years of longing explode the moment he’s sharing a house, a cover, and a bed with Lincoln. The restraint, the tension, the way Lincoln looks at him when he thinks no one is watching. None of it feels fake.
For Lincoln, it’s worse. Carter is temptation, disruption, and the one thing that could tilt his carefully ordered world off axis. Keeping up appearances means staying close. Closer than safe. Closer than professional. Closer than either of them can pretend is nothing.
And in a town full of nosy neighbors, fluffy biscuits, and buried secrets, pretending is getting harder by the day.

Variable Onset is the first book in the Wild Type series, following Lincoln and Carter as they navigate danger, desire, and the cases that keep pulling them together. This second edition features a fresh cover, updated formatting, and light edits.
