Even though I missed the first book of the series I was able to follow the plot lines of "Sanctuary." I found myself taking notes on the different characters ... and there are many! With the main ones being Sonny/Nathan then quite a few more, e.g., Molly, Ellen, Jonathan, Tracy, Kayley and so on down the line. The story begins true to Zombie Apocalypse Genre with the killing of one such then things turn even more dystopian with the first part setting up the second quite nicely. Some of the chapters were epigraphed with pithy quotes one of which I adored: "Stand up for what you believe in, even if you stand alone." This is good writerly advice as well since our craft is a solitary one and we're down in the trenches all alone and thus have to make individual choices by the thousands in the course of humping the muse as in scribbling an entire novel. Circling back to Christopher's novel, he has a fine ear for dialogue and keeps the plot moving right along to the point of achieving narrative drive as in exceeding readers' -- this reader's! -- expectations. I want to see more from this fine writer.
