Tricking an Introvert by May Sage

A successful day for Tessa Michaels is a day when the only person she has to talk to is the pizza delivery guy.
An artist and designer working from home, she rarely steps out of her comfort zone.
Attending a book convention once a year is one thing. She can work herself up to it, and the attendees are more interested in her art than anything else.
But when a hot publicist decides to help her with her social anxiety, her peace crashes and burns.

Cole can’t get enough of the sarcastic, sassy wallflower he’s met at a fantasy con. A successful, handsome single guy, he’s used to getting the women he fancies. When she mistakes his flirting for pity, he finds himself stuck in a self-imposed friend-zone for the first time in his life.
Time to get the hell out of it.
