The book seems to flit about with an inconsistent timeline. It jumps from being incredibly detailed in parts, with pages devoted to shopping, items they found, some they didn't,.... And on and on. Then to a severe lack of detail in other events, one gets shot, and it's hardly mentioned. It it very difficult to get a handle on the time sequence, there seems no logical flow. Survival is relatively easy for these people, they make no difficult decisions, nor are they pushed to make any. They add numbers to their group without thought of consequences. Characters lie dormant and then reappear..... The whole plot lacks any real direction. Now planning a move to Las Vegas,... Really, I live in Northern Ireland, never been to Vegas, but I would suggest a move to somewhere fertile might be a better move.
