What happens when you mix up theology, a downed ship, the Prime Directive, time phases and Paradox?
Read the darn book if you want to find out how it turns out, silly.
I will say this though. This is the Star Trek series set in the Next Gen Universe that I wish had been done, instead or perhaps because of ST: Voyager.
I still cannot believe there are no new series planned for the immediate future, and with the emphasis now being placed on the NEW Star Trek universe, I have to wonder if there ever will be a return to the old one.
