About This Book
In the quiet Maine town of Tranquility, Dr. Claire Elliot is trying to rebuild her life after loss — a fresh start, a new practice, and a chance to steady things for her teenage son. Then the violence begins. Teenagers in town start committing acts of shocking brutality, one after another, with no clear motive or warning. Claire is both physician and mother, and as the incidents escalate, those two roles pull in dangerous directions. Something is wrong in Tranquility — something biological, environmental, or worse — and Claire may be the only one willing to look for answers before her son becomes the next headline.
Gerritsen's background as a physician gives Bloodstream an uncommon credibility. The medical mystery at its center feels genuinely unsettling precisely because it stays grounded — the horror emerges from plausible science rather than supernatural menace. The pacing is tight without feeling rushed, and Gerritsen layers Claire's personal vulnerability into the investigation in a way that keeps the tension intimate rather than abstract. This is a thriller that works on you quietly, building dread one clinical detail at a time.
