Amy Larson & Hunter Forrest FBI Books in Order

Amy Larson & Hunter Forrest FBI follows two investigators whose partnership begins with a disturbing murder in rural Florida. Heather Graham combines a developing romance with crimes linked to ritual, extremist belief, and carefully arranged scenes. Amy works for the Florida Department of Law Enforcement, while Hunter is an FBI agent whose experience includes cults and occult-related violence. Their different roles give the series a continuing investigative team, with a personal relationship developing alongside the practical demands of stopping dangerous people.

Danger in Numbers opens with the killing of a young woman near the Everglades. Amy and her regular partner, John Schultz, investigate a scene that suggests more than an isolated act of violence. Amy’s ability to sketch what she sees has already proved useful in her work, and her attention to detail becomes important as the case develops. Hunter arrives with knowledge of similar crimes. When John is sidelined by a medical emergency, Amy and Hunter must work together, bringing them into closer contact before they fully understand the forces behind the murders.

The landscape offers concealment as well as atmosphere.

Remote parts of Florida allow offenders to operate away from easy observation, while the investigators must connect physical evidence with beliefs and organizations that are less visible. The opening case draws the pair toward a cult, making it necessary to distinguish the people carrying out violence from those directing or encouraging it. Their attraction adds another layer to a partnership already requiring trust. They need to depend on one another’s judgment while facing circumstances in which a mistaken assumption can leave more than one life at risk.

Crimson Summer returns them to a horrific scene in the Everglades. Multiple young men have been killed in what resembles a violent battle, and a small red toy horse suggests a connection to earlier murders. The clue raises doubts about whether the previous investigation reached everyone responsible. Further violence in New York widens the scope of the problem, making the Florida scene look like part of a larger pattern. Amy and Hunter have to follow connections across different places rather than treating each new crime as an independent event.

Begin with Danger in Numbers, followed by Crimson Summer, to meet the partnership and understand the continuing concern with organized violence. The tone is romantic suspense with a strong crime-investigation thread. Ritual appearances and apocalyptic imagery create disturbing puzzles, but the central work involves identifying human choices, motives, and networks. Readers who enjoy an established pair working through related threats will find that connection important here. The developing romance supplies a personal reason to care about their safety, while the investigations repeatedly challenge their confidence that one arrest can bring a dangerous movement to an end.
