Read The Hobbit and The Fellowship of the Ring when I was 8 (the books came with the Spectrum text adventures!:P), and read The Two Towers and Return of the King when I was 9. Kept on getting them out from the library until I was 11 and my dad got me my own copy, all in one massive book with tiny, tiny text! It’s kept with extreme reverence as it means a lot to me, as a) it was my favourite book as a kid, and b)my dad wrote a note inside the cover marking my 11th birthday, so it’s got sentimental value on that front too.
As that copy was starting to get a bit fragile, I bought the Kindle version last year. Still love the book, but yes, the songs and poems can outstay their welcome! 😛 My brother finally managed to read LotR when he was in his late 20s after about fifteen years of trying. It took him nine months – apparently the “three f*****g pages describing Treebeard’s eyes” particularly annoyed him, as did Tom Bombadil. Poor Tom, nobody likes him…
