Permanent Damage (A Valerie Urniak Mystery #1)
Rebecca A. Engel

Valerie gave up a promising career as a psychologist to return to the vocation that put her through school. Her belief is that she's still helping people, but in a much more hands-on manner.
Then, within a period of three weeks, three of her clients die.
Only one is a natural death.
One is a suicide. Valerie cannot accept that she did not recognize the depths of her client's depression. Nor can she shake the feeling that there is a connection between that suicide and another client's murder.
Her penchant for hands-on work leads her to conduct her own investigation into these deaths, much to the displeasure of the detective working the cases. And they both learn that sometimes displeasure can lead to something else...
