The Doorway and Other Stories: http://www.amazon.com/dp/B007SV1FB2
I’m happy to have some of my old stories in one place. Except for The Princess Quest, which is a humorous fantasy, and Old Rex, a ghost story, the rest of the stories are all science fiction adventures of different types, involving aliens, time travel, symbiotes, and humans searching for a home and/or family. All the stories have been published elsewhere–sometimes more than once–over the years, except for Royal Guardians.
