Def not the best book. He crammed a TON of information into one book (as someone who knows nothing about Norse mythology I felt like I was being swallowed), there were like 95 side quests, cliffhangers are GOOD endings (they don't make books "bad"? lol), and although I enjoyed the diversity of characters and meeting Thor and Loki it wasn't his best. Magnus sometimes goes a little too much into Percy for me which sometimes throws me off. It's better than the trash of HoH & BoO, but I wouldn't claim it's the best book he's ever written.

His best book for me is probably TLO or SoN.
