Perfect for you if...

You want a police procedural with genuine spark between characters who have reason to distrust each other.
You enjoy small-town settings where everyone knows everyone and that creates both tension and warmth.
You like your romance grounded in competence: watching characters prove themselves professionally whilst figuring out their personal feelings.

Maybe not for you if...

You're looking for a slow-burn romance. Ava and Eli's chemistry ignites quickly and the focus stays on the case and the danger, not weeks of will-they-won't-they.
You need books heavy on K-9 training details or dog-handler technical expertise. The dog is part of the story but not the centre of it.
You prefer standalone books with no series context. This is book two in a series, though it works fine alone.

About this book

Former big-city police officer Ava Callan discovers a bomb and uses it as an opportunity to establish herself in her new role as a K-9 handler with a small-town police department. She is particularly motivated to impress Eli Thorne, the charming lead investigator from out of town. As Ava pursues her first major case, she and Eli face mounting danger while navigating their intense attraction to each other. This is the second book in the K-9s on Patrol series published by Harlequin Intrigue. Each book in the series is standalone with an uplifting ending.
