Tangled Axon, book 1: Ascension
Jacqueline Koyanagi2013

Alana Quick is the best damned sky surgeon in Heliodor City, but repairing starship engines barely pays the bills. When the desperate crew of a cargo vessel stops by her shipyard looking for her spiritually advanced sister Nova, Alana stows away. Maybe her boldness will land her a long-term gig on the crew. But the Tangled Axon proves to be more than star-watching and plasma coils. The chief engineer thinks he's a wolf. The pilot fades in and out of existence. The captain is all blond hair, boots, and ego . . . and Alana can't keep her eyes off her. But there's little time for romance: Nova's in danger and someone will do anything--even destroying planets--to get their hands on her.
