Trouble at the Turret Station

Publisher's blurb:

Ground Security Turret Station TS4578-933A has served as a means of protecting the remote settlement locations from attackers above. Recently a group of criminal thugs took over the station and modified its laser turrets to allow more firepower and greater range. These villainous goons are shooting down ships and air transports that resist their demands to land and be looted of precious cargo. To make matters worse the thugs have joined alliances with a group of notorious space pirates who want to forge their own outlaw colony in the local area.
