Dead Space by Leigh Kelsey

Floating in deep space, Julia and the crew of the Nerve combat an unseen foe. Every day, more crew members vanish without a trace, and menacing sounds echo through the night. It’s only a matter of time before the monster sets Julia in its sights.
With her dragon mate Kiv, her friend Sinna—a rare alien with a moving star-map on his body—and the infuriating boulder giant, Ruhar, Julia is thrown into a dark, desperate fight for survival. The horror on board is picking them off one by one, and even if Julia and her men escape the Nerve, the shadow will not let them go.
