History of the Lord of the Rings

[cesar.ewok]

I have already read some volumes of the HoMe which correspond to the narrative of the Silmarillion. I hadn't bought those ones talking about the LotR out of lack of interest. However, I have recently become interested in their content (because of the Letters), and I have bought Return of the Shadow and Sauron Defead (these were the only ones available in the store :P; the others I should purchase later). I was wondering what is your opinion about these books...
