I'm just going to say right off that I'm really digging the Jon Shannow books. The Last Guardian is even better than the first volume, Wolf in Shadow. Jon Shannow, while on his endless search for Jerusalem, encounters a young single mother of two, a young gunfighter who wants a reputation at Shannow's expense, reptilian warriors, Atlanteans, a fiery preacher called The Parson, and the Sword of God. Much more background is given to Shannow's post apocalyptic world, fleshing it out, as well as giving more of Shannow's background. Well worth a read but only if you've read the first volume.
