River of blue fire

This second volume in the Otherland series presents the adventures of a small band of hardy, even heroic folk who have broken the Grail Brotherhood's barriers to entering Otherland and are hoping to open the place to the common run of humankind. In the course of this part of its journey, the band encounters giant insects, advertisements coming to life, postholocaust worlds, and treachery from a Grail Brother within their own ranks.
