Distance, takes place in the same time line as Deep Winter, Shatter and Remnant, but with an entirely different cast of characters. I just started it last night, and I like it so far. Of course, I'm still trying to read Remnant at the same time, which means I get pulled between the two stories! For those of you that haven't read the original trilogy, the author makes them available on pdfs for free download. The new story is on his blog. I highly recommend these books - although fiction, there is much to be learned about prepping in them, too.
