Rae Blissfield left her parents' lifestyle years ago, changed her name and went to college to get her degree in accounting. Her parents are part of a Renaissance group where men in tights, skillful artisans, ladies dressing as wenches and medieval weaponry are normal. They are currently in town and asking her for a favor, and since she loves them dearly, she is willing to help in any manner they need. The favor they ask is extremely outrageous, even for her; they want her to accept a mammoth of a man into her home and watch over him. The man is in danger, especially since he has somehow lost his memory and thinks he is in the 16th century. Rae quickly finds they are both at risk.

Conner Larkin is an undercover FBI agent working on a case to find out who in the Renaissance group is printing counterfeit money. He is getting close to answers when he takes a blow to the head losing his memory. After a staged attack draws blood, his friends do what they think he needs and asks their daughter to watch over him. While leaving the grounds, they are followed and shot at, further proof that whatever he uncovered is dangerous. But all he can recall is 16th century warfare, so guns, cars, phones and coffee machines are beyond his scope of knowledge. As Rae and Conner go on the run, nightmares of terrible things he has experienced in his past keep him awake and wonders if he really wants his memory to come back.

THE BLISS FACTOR is an entertaining read, though I didn't get attached to the characters like I did in the previous books. Definitely a decent read.
