Hooked on the Otter Doctor by Delaney Rain

Tobias Ahlberg is a reluctant sixth generation fisherman in a country that no longer wants to support fishing. His entire focus is on getting his stubborn father to follow him into aquaculture, while also earning money any way he can. While he wasn’t looking for love, he’s thrilled to discover that fated mates are real and he’s one of them.
Halaby Revazi has been a ship’s doctor for twenty years and now he’s also leading the medical branch of the delegation to Earth. His stress levels are skyrocketing…and he’s not okay. While on a forced leave for the sake of his mental health, he discovers Tobias is his mate and it brings up a lot of questions about what their future might hold. The human mates of Halaby’s friends have happily given up their lives on Earth, but Tobias has a family that needs him.
Changing their lives isn’t easy, but Tobias and Halaby are determined to get things right this time around.
