I stumbled upon this on Viki, not expecting much, and it blew me away. I watched it in one go and believe me, this is one of those shows that sticks with you and leaves an impression long after you’ve watched it. I originally gave this show a 9.5 because of the ending. However, I changed it to a 10 because, in the end, the rest of the story was just THAT good.

I highly recommend reading the books. They are an easy, exciting read and it will engross you. Don’t expect to get much done because once you start the books, you won’t be able to put them down.
