I highly recommend this book to you all as a good filler of some blanks in the story of Lord of the Rings. It has the account of Isildur losing the ring in the river, and also why King Theoden was really depressed when Gandalf, Gimli, Aragorn, and Legolas showed up.. it has the Battle of the Fords of Isen where Sarumanns army routed Rohan. There is only mention of the stragglers coming to Helms Deep, in the LOTR. It has also a story of Numenor and also more on Galadriel! It is a good read for reference and background filler!
