After finishing the Nikki and Bob Series by Jerry Boyd I dug around in the Kindle Unlimited store and found the Junkyard Pirate Books by Jamie McFarlane.
The 3 books in the Junkyard Pirate series have a lot of tropes from other books I have read, but they definitely tell a different story. I enjoyed reading them enough that once I finished them, I moved right on to the Privateer series also written by Jamie McFarlane.
Overall, I rate the series a 9 out of 10 and recommend them to anyone looking for some fun sci-fi.
