I've loved all of ALI HAZELWOOD's books.  Commonly set in a STEM field with a super, smart main female character who struggles in her male-dominated career.   The latest release, NOT IN LOVE, stays true to the norm with a bit of extra heat. Rue Siebert works as a chemical engineer alongside her childhood best friend in a private company owned by her mentor.  She focuses on her research to develop a barrier to preserve the shelf life of fruits and vegetables.  Rue keeps people at a distance and doesn't do relationships.  When her company debt is acquired by a group of investors, she will have to balance her interest for one of the hostile takeover partners (and last hookup), Eli Killigore.  As fate continues to throw the couple together, they realize they have more in common than just their growing attraction.  With both Eli and Rue resistant to trust and battling for control of the company, they must evaluate how to prioritize their loyalty to their friends when their relationship puts them at cross purposes. The sexual scenes are spicier and more erotic than you expect from Hazelwood.   Fast read that I couldn't put down and finished in only a few hours.  Interesting setting and storyline with fabulous secondary characters that I am hoping we will see more of in her future books.  Maybe best friend's little sister?  Triggers of childhood neglect.
