Star Runners: Dark Space by L.E. Thomas

True friendship knows no boundaries.

Being a recruiter for the Galactic Legion of Planets is a safe and secure job for Josh Morris as he tries to re-enter a "normal" life following his captivity at the hands of Dax Rodon and the Tyral Pirates. But he is tortured by a vow he made to the smuggling group known as the Barracudas to return their ship. 

Once he decides to leave Earth, Josh has no idea his past is hunting him, seeking revenge. What follows is a heart-pounding adventure discovering new worlds and cultures, narrow escapes, and thrilling space battles as Josh travels to the farthest regions of the galaxy—and beyond it into the unexplored Dark Space—to keep a promise and help a friend, unknowingly sparking events leading to a conflict of terrifying scope unlike any the stars have ever seen.

Star Runners: Dark Space is the electrifying fifth entry to the Star Runners Universe: a collection of space adventure books.
