Missing and Endangered by JA Jance

 This is the latest Joanna Brady novel in the long-running series by Jance. Considering that it's set at Christmastime, this has kind of a dark storyline. The 2 main plots involve cyber sexploitation of Joanna's daughter's college roommate and the safety of 2 little kids whose stepfather was killed in an officer-involved shooting. Happy Holidays! They were both good plots. You could see how the naive college roommate could end up being the victim of a sexual predator. And along with Joanna, you worry about the fate of the two little kids living in a violent household where the mother may have been behind the stepfather's death.  Quick read.
