This was a really great story about a professor who falls for his student, granted the relationship starts before they realize that they will be in the same class and facing each other every week. When Eli, the professor, decides that they can't have some hot affair that could potentially ruin his career Ash readily agrees, though they stay friends. What starts off as intense lust builds into a lasting friendship then into love. There's also a bit of a mystery thrown in that helps the story along.
I really liked these two characters together as they played nicely off each other. The sexual tension between the two was pretty hot as was the sex. Even the secondary characters were well written. I would recommend this book to lovers of m/m romance that likes the build-up to a sweet romance.
