I bought the first three and read through them in 4 days!  The story telling style pulls you in and while similarities exist with others from this genre, there are unique twists and fresh ideas. I never felt bored and wanting to skip ahead, not wanting to miss any part of Catrin's story.  I've already bought the next 3 in the series and can't wait to find out how Mr. Rathbone weaves the remaining pieces together, including introducing the next generation!
