Advanced Physical Chemistry (Chemistry Lessons #3)

After four lousy boyfriends in a row, chemical engineer Penny Popplestone swears off men until she can figure out why they keep cheating on her. But her no-men resolution hits a snag when the mysterious and superhumanly hot barista at her favorite coffee shop strikes up a friendship with her.

Penny strives to keep things platonic, but when Caleb gives her the kiss of her life, she realizes he wants to be more than just friends. Tired of always being “good little Penny,” she throws caution to the wind and pursues a no-strings fling with the hottie barista. It’s not like they have anything in common beyond scorching physical chemistry, so what does she have to lose?

Only her heart.

Now, this fanfic-reading, plus-size heroine faces an unsolvable problem. What do you do when being apart is unbearable…but being together is impossible?

Advanced Physical Chemistry is the third in a series of standalone rom-coms featuring geeky heroines who work in STEM fields.
