Lights and Sirens by Lisa Henry

Paramedic Hayden Kinsella is single and the life of the party. He likes driving fast and saving lives, and he doesn’t do relationships—he does hookups. Except he wouldn’t hook up with copper Matt Deakin if he were the last guy on the planet. Hayden thinks the feeling is mutual . . . until clearing the air leads to a drunken one-night stand, which leads to something neither of them was expecting: a genuine connection.

Police officer Matt Deakin moved to Townsville to take care of his elderly grandfather. In between keeping an eye on Grandad, renovating his house, and the demands of his job, he somehow finds himself in a tentative relationship with Hayden and very slowly gets to know the damaged guy beneath the happy-go-lucky persona.

But the stressors of shift work, fatigue, and constant exposure to trauma threaten to tear Hayden and Matt apart before they’ve even found their footing together. In the high-pressure lives of emergency services workers, it turns out it’s not the getting together part that’s hard, it’s the staying together.
