"A Walker mystery"--Spine.

Samantha Turner needed the break from her medical duties in Sheridan, Wyoming. She also needed the continuing education credit certificates the medical examiners conference in San Diego would earn. Now, if she could only get her mind off that morning sickness that seemed to strike at any time of day... In this case, the cure is worse than the disease: In the middle of one of the lectures, a doctor falls over dead, and Sam has seen enough to know that there is something unnatural about it, a feeling her late husband's son, Derek, seems to share. Of course, he's willing to share anything with Sam, and if he's around, he can protect her - a protection she'd just as soon do without. And there's the fact that seeing Derek reminds her of her morning sickness - for a number of obvious reasons. As Sam asks about the doctor's death, more questions crop up. There's an abortion clinic and a less-than-grieving widow; there's a firebombing and a bomb aboard the plane that should be bringing her home. Painstakingly and sometimes painfully putting the pieces together, Samantha Turner discovers what a cabal of doctors has created - and finds that a honeymoon cruise to the Caribbean is not necessarily what the doctor ordered.
