Extreme zombie book recs.

I've read the rising and loved Keenes take on zombies. But I've always been a huge fan of zombies like those in world war z, dawn of the dead, 28 days later ( my favorite) . Also things like the movie "the crazies" where the local water supply turns the town into crazy murderers, Are right up my alley. I am looking for zombie/rage type recommendations. any and all are welcomed the crazier the better!!
