I really tried with this book, i really did. It wasn't bad, per se, but it felt like reading a book about people making battle tactics and not much else. I rarely dont finish a book, but this was one that i had to give up on. I read about half, and then when i went to pick it up again the next night I just couldn't bring myself to do it. I just didn't care and didn't want to keep reading. Maybe it improves later on, but i feel like when you're over 100 pages in and you still dont care about the story or characters, it's not the book for you.
I'm sure there are some people who will love this. Kids who are super into vikings who literally want to know everything about how their raids worked will probably go crazy for this book. But it's just not for me.
