My one-sentence summary of this book: Norse Mythology inspired X-Men, but with extra sex. This book starts out strong (which is one of the reasons why I picked it up), but towards the middle it became super difficult for me to finish, as I found the story very much unengaging. The book was also another reason for me to realize that romance is just not my genre - it just felt cringe to me most of the time, especially considering all the other stuff that was going on in the plot. 

The worldbuilding was great though, and seemed very accurate to me as a long-time fan of the Norse myths.
