Dr. Samantha Love says it’s all about the chemistry. A brainy psychology professor and researcher, Sam has based her entire academic career on the theory that what we call love is simply a chemical reaction. She is currently running a study to prove that her compatibility blood test reveals perfect matches—sort of like an organ donor, but for relationships. No romance required. 

 

Along comes sexy literature professor, Dr. Ethan Quinn, who says it’s all about the romance. He thinks the pretty psychology professor has taken love and all its mysteries and reduced it to something as romantic as a cholesterol test, and he sets out to prove her theory wrong.

 

When Ethan signs up for her study, Sam discovers to her horror, that according to her compatibility test, they are a perfect match. Sam faces an existential crisis over her career and her research. If she believes in her science, shouldn’t it follow that she believes Ethan is her perfect mate? And if she doesn’t believe he’s her perfect mate, doesn’t that bring into question her research? Her compatibility test? Her reputation? And her very career? 

 

As Sam struggles with her dilemma, Ethan pursues her with all the romantic tactics in his arsenal. Will Sam’s theories succumb to his challenge? Or will Ethan lose the battle for Sam’s heart?
