Rockets Full of Rubies (T.J. & Luna Book 7)

A red dwarf star hosts a planet with a strange ring of small rockets orbiting it - leftovers from an ancient war. Inside, their cargo holds are filled with rich red rubies. Two couples hoping for a vacation getaway stumble onto the mysterious ring and attempt to chase down the source of the lustrous gemstone. When they discover more than they possibly could have imagined, they seek out an old friend to help market some of it. But corrupt officials lay a devious trap in the background. Surprised and captured, only the promise of a new and powerful weapon can offer salvation from certain death.
