Love any thing by Heidi Betts.
Interesting story of a female Pinkerton agent.
Finally! A heroine who's not a virgin and not a mother. Part of a family series, but don't know the other books.
Loved it.

Pistol-packing Pinkerton agent Willow Hastings always got her man -- until handsome, yet arrogant, security chief Brandt Donovan interfered in an arrest. Now she's been ordered to collaborate with Donovan to catch a killer, but she ends up wondering if he can capture her new partner's heart as well.
