Tin Machines is #5 in the Star Sails’ series.
Limping on their way home, the crew of the SS Falcon is in desperate need of supplies. The most important is gluonite so that they can get their hyper drive working.
Without faster than light engines running, it’ll take them close to 30 million years to get back home. That’s a little longer than the estimated life of the good ship Falcon.
They stumble upon the Ralens, an advanced alien race who have been overrun by their robotic laborers they call The Unknowns. If they can help the Ralens, Captain Stone, and his men might be able to grab some much-needed supplies.
But why has Scot Free, their android, gone rogue and trotted off to join the Tin Machines?
