The Echo Series by Belinda Crawford

In the dark, empty space between solar systems, something lies in wait.It’s pretty easy being a ship kid; clean out the cyclers, avoid your sister, don’t get sucked into space. The hardest bit about it is spending a couple of decades in stasis/sleep while your ship travels to the next solar system. Then rinse and repeat all the way back to a home you’ve never seen. Except Kuma just got kicked out of stasis early, like decades early. And he’s alone.All. Alone.Except for the fug.
