I like these medical mysteries. This one is by the same woman who wrote the medical space mystery that I enjoyed last month. This one is similar in some ways. Something is making the teens in a small Maine exceptionally murderously angry. A new doctor just moved to town to help her own teenaged son with his anger and behavioral problems afte the death of her husband, his dad. She finds the typical New England smalltown stuff a little hard to handle -- unfriendliness, reticence -- and this gets worse when she believes that there is something biological behind the temper outbreak.
There is a little too much weird medical dialogue that doesn’t add to the story, in both this and the other Gerritsen book I read -- seems to be a way for the author to establish bona fides early on -- but once you get beyond that (in this case an admittance to an emergency room where the doctors yell drug directives at each other for a few pages and you’re left thinking "huh?") and the story starts to unfold you appreciate that the author can also describe characters and not just diseases.
