Space Pirate Reunion (Viraquin Voyage Book 4) by C.G. Harris
The space pirate life is never easy... Ben and Lois are closer to reuniting Bubbles with her long-lost alien mother, but just because they're closer doesn’t mean it’s going to be easy. They must face off against an army of spiderbots, killer mushrooms, and a colossal cave monster the size of a '69 Buick! To top it off, Buttercup finds herself in mortal peril and our dynamic duo have no idea how to save her. So it leaves a big question hanging out there; Will Ben and Lois conquer these outrageous obstacles, save Buttercup and achieve the most epic reunion in the galaxy?
