I really did enjoy this book. The only thing I regret is not reading it sooner, more specifically, not reading it before I read The Sword of Summer (The first book in the Magnus Chase series). The two books have a lot of similarities but fortunately they were different enough that I was able to enjoy both and I did not feel like I was reading the same book twice. I am just hesitant now to read further into these two series because I will just expect them to be the same. Perhaps Mr. Riordan needs new inspiration and some creativity and hopefully does not begin another new series with the same plot as these two.
