Huge fun. Most of the book is taken up with the final battle against Surtur, and it's fantastic. Gigantic battle scenes, huge casts of recognizable characters, the works. This part of the book was great. The Lorelei subplot finally gets resolved, thank goodness, because it was really becoming a drag on the book. Interesting how Simonson made Thor a supporting character in his own book, which is fine by me. This version of Thor is... less than bright, and characters like Beta Ray Bill and Sif make for much more compelling reading.
