In Gateway to Nifleheim, Glenn G. Thater delves into the Germanic world of gods and goblins that are related to Valhalla and Nifleheim, the powers of good and evil to spin her yarn. This is the first book in the Harbinger of Doom Series. I have to confess at the start, I skipped many a page to keep going. The story doesn't so much move as that it plods on, tediously.
