Cuts Like a Knife by M.K. Gilroy

[Ray]

From Google Books:

 

Chicago has a new resident—a heartless killer on a long crime spree. Kristen Conner (think Sandra Bullock in Miss Congeniality) is a good cop and a good girl: she loves her mom, goes to church and coaches her niece’s soccer team. And her track record and instincts as a detective are impeccable . . . but this case and this killer expose a blind spot that ultimately endangers those closest to her. Can she catch this hauntingly familiar culprit before he strikes again? Cuts Like a Knife is loaded with action, humor and wry introspection.

    

     I could have done with less wry introspection, but I will be reading the sequel.
