The Saint by Kimberly Kincaid

His partner’s most trusted informant is his only hope…and his only weakness.

When Detective Liam Hollister is assigned to an assault-turned-murder, he brings his signature three “C”s: control, calm, and composure. The “C” he wasn’t counting on? His partner’s informant, Carmen Desoto, who’s not only the key to unlocking his case.
The sexy, sharp-tongued nurse is the only person who’s ever gotten under Liam’s skin. Driven him crazy.
Made him want the one thing he can’t have.
And now they have to go undercover together to catch a killer.
Liam knows he must keep Carmen at a distance, no matter how hard it is to resist. But when the scheme they uncover puts them directly in danger, distance isn’t an option.
They’ll have to fight together if they want to make it out alive.
