Hagan Books in Order

Kay Hooper’s Hagan series, also known as Hagen or Hagen/Raven, is a group of connected romantic suspense novels. Its stories bring together people involved in covert work, dangerous investigations and hidden identities, with each book giving a different couple the central role. The romantic problem and the outside threat develop together, so getting close to another person can complicate a mission as much as help it.

The sequence begins with In Serena's Web and continues with Raven on the Wing. In the latter, Josh Long becomes fascinated by Raven Anderson and tries to find out who she really is. What he discovers seems to put her beyond his reach, but Raven’s circumstances are more dangerous than a simple background check can explain. Her efforts to keep him at a distance make the truth part of both the suspense and their relationship.

A convincing cover can create real feelings.

That problem is especially clear in Rafferty's Wife, where cryptographer Sarah Cavell and federal agent Rafferty Lewis pose as newlyweds on a Caribbean assignment. Their task involves coded information and a threatened revolution, while the supposed marriage puts them in an intimacy neither can treat as purely professional. Sarah’s ability to solve codes does not make Rafferty’s guarded emotions equally easy to understand, and his experience in the field does not remove his personal vulnerabilities.

The settings and assignments vary across the books. Unmasking Kelsey takes an investigation into a company in a southern town, where a woman trying to protect her younger sisters becomes important to the case. The Fall of Lucas Kendrick reunites an undercover investigator with someone he left behind, bringing old hurt into a new operation involving stolen art and illegal weapons. These changes of place and circumstance keep the connected series from being a single extended mission.

Later entries include It Takes a Thief, involving a woman who wants to reclaim her family’s plantation and a federal agent working behind a gambler’s identity, and Aces High, which reunites two agents after apparent betrayal has separated them. Again, the practical task requires cooperation while the personal history makes that cooperation difficult. People who can manage an undercover assignment may still misread someone they care about or hesitate to ask for help.

The tone is romantic suspense, with attraction, deception and danger sharing the page. Readers can follow publication order to meet recurring connections as they emerge, beginning with In Serena's Web and Raven on the Wing. The changing couples offer different versions of the same central challenge: deciding how much trust is possible when someone’s work, history or identity remains partly concealed. The series suits readers who want the relationship to remain central even while a criminal threat demands attention.
