Here's a crazy idea- don't like zombie apocalypse novels?
THEN DON'T READ THEM.
There are countless- *COUNTLESS*- post-apocalypse novels out there sans zombies, from Hubbard's "Final Blackout" published in the 1940s (and numerous, numerous predecessors), to Cormac McCarthy's 2006 "The Road," and onward.
Not hundreds- *thousands.*
Go read them, and quit whining about the fact that something else exists- the entire literary pantheon doesn't revolve around your narrow little view.
i would simply reply to your querry in a manner somewhat angrily and militant as you put forth your manual pontification, here we go, first off, there ARE post apoco books that have indeed been scribed. perhaps you are a bit feeble to seek them out. but quite simply, if you do not enjoy the subject matter that has indeed been "played out", by all means, find a different subject matter to read about. there is a vast assortment of fiction literature in the world today, some apoco and some non so much. you shouldnt gripe and complain about one certain genre, quite simply, if you dont like it.... dont read it, jerk. some people enjoy that played out same ol same ol, prolly because in that world short tempered, (and im betting) easily angered pansies, such as yourself would have been loooong gone after the first chapter. quite simply:most people thar procure and engage in these repitoire of such zany and wacky fiction, is to mentally escape from a world that is full of closed-minded impatient "butt dongles" (thank you G.Kincade) such as yourself thank you for you time, im off to read a "played out" monotanous zombie book. you really should find something more relevant to whine about. butt-bag.
