The Long Way to a Small, Angry Planet by Becky Chambers.

A rollicking space adventure with a lot of heart

When Rosemary Harper joins the crew of the Wayfarer, she isn't expecting much. The patched-up ship has seen better days, but it offers her everything she could possibly want: a spot to call home, a chance to explore the far-off corners of the galaxy, and some distance from her past.

And nothing could be further from what she's known than the crew of the Wayfarer.

From Sissix, the exotic reptilian pilot, to Kizzy and Jenks, the chatty engineers who keep the ship running, to the noble captain Ashby, life aboard is chaotic and crazy—exactly what Rosemary wants. That is until the crew is offered the job of a lifetime tunneling wormholes through space to a distant planet. Sure, they'll earn enough money to live comfortably for years, but risking her life wasn't part of the job description.

The journey through the galaxy is full of excitement, adventure, and mishaps for the Wayfarer team. And along the way, Rosemary comes to realize that a crew is a family, and that family isn't necessarily the worst thing in the universe…as long as you actually like them.

This has gotten some rave reviews from io9 and some other places, but I will say that it's hard to get a hold of if you want to get it from a library. I'm personally really excited about a space opera that apparently was originally self-published, but got so much buzz that it was re-released with a major publisher.
