It took me awhile to get in to this one and that might be because it started off pretty slow. Almost half the book was set in modern day, which was alot more than I was expecting. The first half also kind of felt like a training montage which I found kind of boring and unnecessary. Once we got to the Viking times I enjoyed the characters but I didn't feel very convinced by the relationship - I feel like they didn't build enough before getting together. I would have liked to get more of the lore and world-building as well. I don't think I will be continuing the rest of the series. I just wasn't invested enough by the end.
