Love in the Lab by Julie Milo

She’s determined to avoid distraction, no matter how good he may look in a lab coat.

Molly Delaney sticks to three straightforward rules to remain focused on her coastal environmental science research in New Orleans. Stay in the lab, stay on schedule, and stay away from distractions—especially dating.
Then the first and second rules are washed out to sea when her archnemesis, Jonathan, is paired with her for fieldwork outside the lab. She can still stick to the third rule, though—Jonathan’s charm and stupidly handsome face are not enough to tempt her. Especially when he insists on distracting her from work with childish pranks.
As they spend time together outside the lab and off schedule, she learns that he is also thoughtful, protective, and intent on getting her to leave her microscope behind for some much-needed fun.
But Molly knows how this ends. She can’t let her own distractibility jeopardize her research. Not again.

Love in the Lab is a closed door/just kisses, enemies to lovers, workplace romcom featuring two nerdy scientists and ADHD representation. It’s the second book in the interconnected Delaneys in Love series, but may be read as a standalone.
