Following a bit of post-apocalyptic bent( my vice!) I just finished a book called "Kingdom Come: Abaddon"...only seems to be on Amazon from what I can see. Definitely a different take on the theme, especially location wise( not the good old US for once!)...and relatively contemporary. Not the longest to be fair ( though obvs heading into a series), and starts slightly slowly, but it picks up and rolls through well. Kept me reading anyway.
