Wounded Earth by Mary Anna Evans
An environmental thriller from a recipient of Red Adept's Red Adept's Annual Indie Award--
Larabeth McLeod has beauty, money, several patents, a Ph.D., a successful environmental firm, and some very old secrets. When a man with the uncomfortable name of Babykiller begins stalking her, terrorizing her with stories of her darkest days in Vietnam, stories no one else knows, she feels compelled to fight back...until he exposes her most tender secret of all by threatening the daughter she has never met.
She turns to private detective J.D. Hatten for help, breaking five years of separation and silence between quarreling friends. And then Babykiller shows his true capabilities. He is the head of an illicit business offering but one service--moving cargo worldwide for criminals who need their drugs or cash or smuggled goods shipped safely and anonymously--so he is capable of putting anything anywhere. He quietly explains to Larabeth, a well-known environmental executive, that he can even put defective gauges in nuclear power plants, and he will, just to get her attention. If she goes to the police for protection, people will die. Lots and lots of people will die. And one of them will be her daughter.
Larabeth and J.D. are just a normal man and woman, up against a babykiller. But then, Babykiller doesn't know who he's dealing with...
