As for the plot? Well, it sounds like a fairly traditional time travel yarn, one where the folks in a dying tomorrow head back to the past to change how history unfolded so as to sve themselves from extinction, but that's all I know of it.
This is another release wherein I've a relationship with the distributor, and I believe I've been promised a complimentary copy for coverage on SciFiHistory.Net. But sometimes those things fall through the cracks, and -- as I've said before -- some outlets don't mail out those copies until all of the retail surge has been handled (gotta make a buck first, I understand that), so I'd encourage regular readers to watch this space: if one does show up, I'll be happy to give this one some added promotion as it's right up my alley.
Folks interested in making a purchase can head over to Amazon.com. It looks like they're in short supply at present.
As always, thanks for reading ... and live long and prosper!
