STEM Heroines in Romance ― The Master List

Welcome to the one and only STEM Heroines in Romance master list!!! There are over 170+ books featured including Young Adult, New Adult, and Adult romances from every genre. And I plan on updating the list as I find more.

As an Astrophysics Major and an avid Romance reader, seeing STEM heroines in Romance warms my heart. I love watching heroines navigate their careers in STEM along with, of course, their love life. But, finding STEM heroines in Romance is difficult. Even when there is some mention of a heroine working in STEM in the description, it’s typically vague and simply says “scientist” or implies they work in tech. I created this master list in hopes of making it easier for people to find Romances to read and love based off on the heroine’s field in STEM.

♡ – Books I’ve read, liked, and would recommend
