Huge buildup for the final showdown. Cruel, dark and gory.
Full of psychos, the worst of which is obviously Victor Helios aka Frankenstein. (I had always thought he was a bastard, but these books give the word a grat depth and vibrance)
This book moves along the story which was begun in The Prodigal Son and sets us up for the ultimate battle of good vs. evil. However the actual end of this story is still at least one book away.
