Looking for good post-apocalyptic/ zombie apocalypse audiobooks that aren’t The Road or World War Z.

I’ve listened to both of those, along with The Dog Stars (excellent), Hatchet (not zombie or post-apocalyptic, but still), and now listening to the third Mountain Man audiobook, Hellifax. Please, no YA; I very much prefer adult-oriented books/ audiobooks with all the explicitness and gore.
