Query: Brust, for worst

When Brust is good, he's outstanding. When he's not, he's atrocious. This is atrocious. As an anti-God screed, it still comes over as fingernails on a chalkboard. I love the early Vlad novels; he lost that flickering talent somewhere, and this is some of the slop that took its place. Maybe it's his politics combined with his anti-religious viewpoint that dogs his steps, but I sure wish he'd get a grip. For pity's sake, he killed off Tazendra. ('nother book). Tazendra! I ask you, can the man be other than mad to his marrow?!
