Oh is this series good.
I believe this book takes place only over a few days but it is jammed packed. Tamsin going through all of the emotions of having to unlearn all of the things she's been told her whole life is done well. Learning that all of the boys that have been sacrificed didn't need to be, having her own power and desires suppressed, the Vikings not being barbarians... what a journey she is on.
The development of the magic between Tamsin and Thrain and then potentially the other brothers, INTERESTING!
I can't wait to listen to the next book.
