"Bernstein has written a smart, compelling mystery set in the fascinating world of fertility medicine. With so many believable suspects, In Vitro will keep you guessing right to the end." -- Mary Marks, bestselling author of the Quilting 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 solve a murder, plan a wedding, attempt a pregnancy and grieve for a friend and colleague.
