I've been reading a lot of zombie apocalypse fiction over the last month or so - this is definitely one of the best to-date.
The story is set 17ish years after a terrible plague zombified much of the USA. The church has taken charge of the governance of the survivors and rules with an iron fist. Science is reviled, free thinking isn't tolerated, and a kind of National Service has been enforced so that everyone takes a turn at the border between safe territory and the zombie infested wilderness.
The characterisations are pretty strong, and the plot gets under way quite quickly. There's a really tense build up to the moment of first zombie contact and I really got immersed into the struggle for survival.
An excellent piece of writing all round. Definitely recommended if you like the genre.
