Query: There is no ending!!!

Not a bad zombie novel at first,tense,suspenseful,and the uber zombies ***SPOILER ALERT***that are intelligent,organized,and can drive and shoot are great.The army guys are slumming from Swan Song,another post-apocalyptic novel.The problem really lies in the fact that THERE IS NO ENDING TO THE BOOK!! It just stops as if the publisher ran out of pages,or the writer suffered a sudden attack of appendicitus.Extremely frustrating and unsatisfying to read.
