Loveless (Crownover), book 2: UnforgivenJay Crownover2020

Hill Gamble is a model lawman: cool and collected, with a confident swagger to boot. Too bad all that Texas charm hasn't gotten him anywhere in his personal life, especially since the only girl he ever loved has always been off-limits. But then Hill is assigned to investigate her father's mysterious death, and he's forced back to the town - and the woman - he left behind.

When Hill left Loveless, he broke Kody Lawton's already battered heart. And now that he's working on her father's case, avoiding him is impossible. She can handle Hill and her unwanted feelings - until he puts his life on the line to protect her. Suddenly, Kody realizes that Hill could be taken away from her...for good.
