Forbidden Professor by Ashley Zakrzewski

What do you do when the chemistry is off the charts, but rivalry is real?

Easton’s been working to develop a cure for Parkinson’s, the awful disease that killed his grandmother. He’s made it his life’s mission to find that cure, but one woman threatens everything.
Isla’s job isn’t easy as a professor, but it pays the bills and she took a job as a freelancer to stuff her retirement. Contracted by Easton’s company to determine if their resources are spent correctly makes her the enemy to all she meets. Especially the attractive scientist, Easton.
