7/1/18 - I think my feelings for this book has changed and will be unhauling it which is the reason I cleared my rating. Though I'm leaving my original review and thoughts up.

I absolutely adored this book! Rick Riordan​ continues to blow my mind with every story that he writes, this one being no different. I haven't read or heard of many books at all involving Norse mythology so this was a very interesting book to read and really enjoyed that take on it.
Rick never fails to make me laugh in every single one of his books as well. I was absolutely living for Magnus' sarcasm and considering I use sarcasm like a second language I related to him a lot with that.

A great story line, great humor, and a lot of good action mixed in makes this an amazing book. I would 100% recommend this to anyone who loved Percy Jackson or loves any sort of action and mythology.
