First of all, render unto Caesar what belongs to Caesar: this book is a book (No 4) by Christopher Tolkien (son) as part of the series of 12 volumes published by him which analyzes the writings of his Dad respectively The Book of Lost Tales 1 (1983), The Book of Lost Tales 2 (1984), The Lays of Beleriand (1985), The Shaping of Middle-earth (1986) which is the book that interests us here, The Lost Road and Other Writings (1987), The Return of the Shadow (The History of The Lord of the Rings v.1) (1988) The Treason of Isengard (The History of The Lord of the Rings v.2) (1989) The War of the Ring (The History of The Lord of the Rings v.3) (1990) Sauron Defeated (includes The History of The Lord of the Rings v.4) (1992), Morgoth's Ring (1993), The War of the Jewels (1994) and The Peoples of Middle-earth (1996). So this is not a new "JRR Tolkien" but an analysis of his manuscripts by his son (not a big deal you might say but Simarillion is to JRR Tolkien and C. authors, brief father and son).
The problem is that when you have to read the Lost Tales and Lais of Beleriand (Volume 3 of the series if you followed!) That will delight
poetry lovers, we remain a little hungry ... especially in the series there are others (not translated) a little more interesting (eg
number 5 "The Lost Road and Other Writings" where one finds connections with CS Lewis (author of the Chronicles of Narnia), the Annals of Valinor Belerian and Quenta and the Silmarillion (again!).
In short, a book to book to those who do not read English (it is better if you can, read the original) but especially the fans because it's not the most interesting for my taste and the price is a bit high for what you get out in the end. Rest beautiful cards in color and black and white but in my opinion a work that is not essential (Argh, I'll still treat me reader who believes all about Tolkien by Felagund! M'enfin it is I think that huh ??)
