Falling for My Rival by Dakota Davies

One night changed us forever.

For one night, we shared our wildest fantasies, our dirtiest desires. Even though it was the best night of my life, I knew I needed to let her go.
Three months later, she walks into my office looking just as tempting as ever. The problem? She’s here to steal my promotion, the same one that will make all of my sacrifices mean something.
Turns out all that heat between us makes us impossible work mates. Half the time, I can’t decide whether to fight with her or bend her over my desk.
But when the verdict falls, I’m faced with an impossible choice: fight for my dream, or surrender to my heart.
