Born to Die : Montana series, book 3

At first Kacey Lambert thinks it's a sad, strange coincidence. Two women with an amazing resemblance to the small-town doctor die suddenly.

But detective Selena Alvarez suspects otherwise. An autopsy confirms that one of the women had traces of poison in her blood ...And Kacey has started to notice ties between the dead women's lives and her own. They were all close in age. They were born within a few miles of each other. And they all have ties with Trace O'Halleran, the single father Kacey is dating. Soon more lookalikes are dying and as the body count rises, the killer gets bolder and more brutal. All Kacey knows is that it's only a matter of time before hers is the next name on a list of those who were born to die.
