Against The Law by Kat Martin

At thirty–two, Devlin Raines is 'mostly retired' from Raines Investigations, and content to run operations from his sprawling Arizona home. But he's never been able to say no to a beautiful woman– so when Lark Delaney comes to him for help, the former U.S. Army Ranger from Wind Canyon gets back in the game.

Lark is sexy, successful and dedicated to tracking down the baby girl her sister gave up for adoption. It should be a straight–forward case, but it's not long before Dev uncovers a shady adoption ring, and worse– a kidnapping and murder.

As the case grows dangerous, Lark needs him more than ever. Dev can't ignore his growing attraction for her, nor can he trust his judgment with women or the emotions he's long–since buried. But there's a chance– if he gets this right and saves Lark's niece– that he'll end up saving himself, too.
