Three Investigations and Three Different Challenges

Every case Hannah Jacobs faces in the trilogy carries a real threat. None of them look the same and none are investigated the same. One begins quietly almost innocently. Another erupts from a disappearance that spirals into something far more dangerous. The third emerges from a cold case that refuses to stay buried. Hannah approaches each investigation with a different point of view, instinct, and a new angle of danger. She is trained to decode patterns but each threat changes the pattern.
