NEW! In Vitro: Hannah Kline Mysteries Book 5 

In Vitro

The fifth exciting story of the Hannah Kline mystery series

Conceiving a second child is supposed to be easy but when Mother Nature refuses to cooperate, obstetrician Hannah Kline finds herself in the uncomfortable role of an infertility patient. Her in-vitro fertilization procedure is on schedule until her doctor disappears, and Hannah and her partner Detective Daniel Ross, are plunged into the middle of a murder investigation.

Dr. Louise Waldman was the well respected senior partner in a leading infertility practice, but Hannah and Daniel soon learn that Louise had an undercover life and dangerous secrets. While Daniel pursues the forensics and a domestic terrorism connection, Hannah investigates a shady business deal and an old romance turned sour. Both are determined to bring Louise’s killer to justice, but it isn’t easy to simultaneously solve a murder, plan a wedding, attempt a pregnancy and grieve for a friend and colleague.
