Gabriella Evans' life consists of proving terms of definitions. An intelligent woman, Gabby is writing her thesis on Duality Principle, saying that if a theorem is true, it remains true if each object and operation is replaced by its dual. Being in Portland, Maine and staying at her deceased grandmother's cottage near the ocean, she intends to prove to herself that she can't be both sides of the coin and has to pick one or the other-but not both. The nerdy, super smart girl has a hidden rebellious appetite for kinky hot sex.

Every day Gabby longs for the hot guy in leather driving the motorcycle, anticipating he could fulfill all her bad boy fantasies. Her friend Jamie finally coerces her into accepting a blind date with Connor Starks, a computer programmer geek. He seems nerdy in spite of his hot looks, just too polite to lose control the way she fantasizes about. Every time they reach the point of getting down and dirty, Connor returns to the nerdy guy with an apology. It is taking everything Connor has in him to be a controlled geek because Gabby is surprisingly someone he definitely wants and needs to hide is wild side. Together, can they prove she can be both sides of the coin and love both the rose and its thorns and can Connor be the bad and good boy?

Explicit sex is the least of this story. What you see is what you get is not this girl with all her hidden sexual fantasies and desires. Matched with this man, she gets it all. THE DUALITY PRINCIPLE is the first I have read by Rebecca Grace Allen, but her story completely captured my attention. It may be a short story, but it is packed with plenty of hot sex. She writes a very interesting and easy to follow story with a hot and emotional plot throughout.
