Proper ladies sketch flowers. She dissects jellyfish. Lydia Pemberton can identify any specimen, but she’s never understood people. Too odd for society and too female for science, she stows away aboard a ship to document marine species and claim her place in natural history. Dominic is a duke by birth and a sea captain by choice, flouting tradition to save his floundering estate. When he discovers an unpaid passenger in his cabin, the sensible response would be to turn back. But what’s one more risk? Falling for the captain wasn’t part of Lydia’s research plan. Neither was realizing her quest for recognition could cost Dominic his solvency. For the first time in her life, she understands people perfectly...so she perfectly understands her impossible choice: Abandon all her dreams, or misclassify the only heart she’s ever wanted to claim. This lightly spicy Regency-era novella features a neurodivergent heroine, a cinnamon-roll hero, and found family on the high seas.
