haven't read X events, is it fiction?
i've read all of Rawles books, patriots was great, his follow up was good. . . and his non fiction stuff was very good.

try to find "one second after" by William R. Forstchen another worth while fiction. . .

some other books you may enjoy

Alas Babylon - Pat Frank
Flashman - George Macdonald Fraser
How_to_Survive_the_End_of_the_World_as_W_-_Rawles__James_Wesley ---more of a guide book
Outpost - Adam Baker
The Old Man And The Wasteland - Nick Cole
Tooth & Nail - Ian Rankin
Wastelands__Stories_of_the_Apocalypse by Night Shade Books
Z.A. Recht - Plague Of The Dead

thanks for input and extra books to add to list, Entopy X-Events is non-fiction by a "complexity theorist" The science lingo is a bit tough to get thru. I am enjoying Patriots, little yeah-gotta do that still moments with what I've read so far.

Resistance by Daniel Kella
Cold Plague by Daniel Kella
Pandemic by Daniel Kalla (loved it)

Earth abides by George Stewart
Alas Babylon by Pat Frank
The last centurion by John Ringo (interesting writing style)
World Made by hand by james howard kunstler (extremely good)
The Fountainhead by Ayn Rand
One second after by William R. Forstchen (great read)
Patriots: surviving the coming collapse by James Wesley Rawles (one of the best reads)
Survivors: a novel of the coming collapse by James Wesley Rawles (not as good as patriots. . .)

i haven't read them all, and i haven't listed the "classic" like animal farm, or lord of the flies. . . all are part of my "fiction" library. . . the books above are actually EOTW type books. . . for the most part.
