Give Me Butterflies by Jillian Meadows

Millie loves her job as an entomology curator, inspiring museum visitors every day. She even has an interview for the department director position, so she can take on an even bigger role in the museum. She refuses to be distracted by her grumpy coworker with his permanent scowl, bright blue eyes, and nerdy astronomy ties.
. . . Not that she’s spent much time noticing any of those things.

Finn Ashford doesn’t mean to glare at everyone, but he’s juggling his job at the museum, navigating the grief of losing his sister, attempting to make his nieces smile, and not ruin dinner for the fifth night in a row.
When Millie stumbles through the door of her interview, her eyes scan the committee and land on the one man that could derail her promotion, but it just so happens he’s also the one man that could make all her dreams come true.
