As many people I started reading this after watching the TV Show (but haven't played the game, yet).

I was scared that it would be too similar to I was already seen but to my surprise, even though some of the events tell the "same story" (on a sense), the events within them are pretty different from what I saw on TV. Different enough I would say.

I did enjoy it though it was short in length, but in exchange you don't necessarily need to continue reading the rest of the books if you don't want to (right away) because it contains a tale per chapter that even if they are a full story when read in full it doesn't put the reader in a position where it needs to read the rest right away.

I recommend it if you like the fantasy genre, is a light read, short and self-contained.
