Desert Rage (Lena Jones) by Betty Webb

When the family of a 14-year old is slaughtered she and her boyfriend both confess. PI Lena Jones is hired by her the girl's biological mother to prove her innocense. Soon there's someone after Lena, going so far as torching her house.
Lena investigates the secrets of the girl's family, meeting a lot of suspects and finding out what a peculiar man the girl's father was.
Lena is a pretty lively character and the Arizona setting is brought to life very well. The mystery itself is pretty satisfying, and there's a nice amount of twists. I did however think the pacing was a bit slow, the book could have done with 50 pages less for me.
All in all, solid enough for fans of female PI's.
