I never bought a book without having read reviews first, but the synopsis was too interesting for me to pass it up. I thought it would be a beauty and the beast kind of story, but it turned out Ragnar was hot! Well, at least in my mind's eye.
This book was just a little bit shy of 5 stars, for me, and that was because its predictability.
The characters were interesting, the storytelling was compelling, the dialogue was great. I especially liked when the character couldn't find the right words in the foreign language - it made the story more authentic.
Ultimately, I judge a romance book by whether it gives me butterflies in my stomach at least once while reading it, and this one did not fail to do so - twice.
Plot-wise,it was predictable (both Ragnar's issue and its resolution), and could have been less-cleanly resolved. I still enjoyed the ride, hence the 4 stars I've given it.
