Wow, i finished reading this in a day, I bought it during the afternoon. This series has made me cry so many times. After reading all of the books, you realise that the core themes are friendship, love and self sacrifice. The friendship that Abbey and Kirsten have and the love that they both feel towards each other. Theirs is a special bond. The love that Abbey and Caspian have and how they can only touch once a year. I loved the whole series, the first book was actually sitting on my shelf for a while before I finally opened it, and when I did I was hooked. There arent many books like this out there.
