To get a good sense of this book, imagine the plot of the first Terminator
Oh, and there's a vampire subplot which seemed completely superfluous to the main plot (likely because I've not read any of the Kyndred novels) but doubtlessly will bring fans of the old books joy and will possibly have something to do with the eventual conclusion of the series.
All I'll say is that I was really hoping that by having vampires and a Terminator in the same book, the least you can do is use 'em to kill off the Terminator. Now that would be a sweet fight.
