Some of the books I’d recommend have already been mentioned but I’ll repeat them.
Terry Brooks, The Shannara Series: I read the Sword of Shannara shortly after it was first released in 1977 after a good friend recommended it because he knew I was at the time obsessed with The Lord of the Rings. I’ve still not read all of the books in the series, in fact I’ve just purchased the three volume set of Jerle Shannara. All of the books are suitable for ages around 10 and older. Though they may be okay for some younger children depending on their attitude to such fantasy.

Tolkein: The Hobbit and as they get a little older the Lord of the Rings Trilogy. I’ve read the books at least 20 times in my life time from the first time I bought the trilogy as a deluxe acid free three volume set, with pull out maps, which I’ve still got 50 years later. I’ve even watched the movies countless times, though I was disappointed that the director cut a significant portion of all three books for example Fog on the Barrow Downs and Tom Bombadil. Then did the opposite with The Hobbit creating four movies with content that was never included in the original story. Still, I love watching them. in fact I’ll start another session this evening. 
Fritz Leiber: Fafhrd and the Gray Mouser I bough a collection of Fritz Leibers short stories (thanks to a kind donation from my gran) in a deluxe limited edition six volume set after reading one of his short stories that referred to these two sword and sorcery characters and was hooked. It’s great reading material for a bed time story, especially considering that they were short stories. By the way, the collection was stolen when I was a university student and to this day I keep meaning to track down a copy of the set as it was beautifully illustrated and bound.
Roger Zelazny, Nine Princes in Amber. It was his brilliant series that my book store owner recommends and the first Zelazny novels I’d read. Two of his novels i.e. ‘Here There Be Dragons’ and ‘Way Up High’ are ideal for the young reader as they were specifically written for children.
Ursula K. Le Guin: The Earthsea Trilogy, I gave my hardback copies to my eldest daughter many years ago . I have fond fond memories of reading A Wizard of Earthsea and The Left Hand of Darkness. I’d alsways hoped to read more of the world. Pity the movie bombed… These are definitely suitable for the younger child.
Robert Heinlein: Glory Road, Stranger in a Strange Land, Have Space Suit, Will Travel, Time Enough for Love, The Moon is a Harsh Mistress and Space Cadet. I initially got Space Cadet out of the Junior library after my English literature teacher who used to tell us a short science fiction story every Friday afternoon as it was the last lesson of the week. He inspired me to try reading science fiction myself and Space Cadet was the first ever science fiction story I read. I later bought the hard back book out of my paper round money and still have it 55 years later. I used to call into my local book shop on the way home from school every Friday and was often given books at massive discounts and sometimes for free and would usually spend all of my paper round money and the money my gran gave me regularily buying all of the regular Sci Fi writers of the time (l960’s & 70’s) such as E.E. Doc Smith, Michael Moorcock, Samuel Delany, J.G. Ballard, Madeleine L’Engle, Anne McCaffrey, Philip K. Dick, Stanislaw Lem, Arthur C. Clarke, Frank Herbert, Isaac Asimov, James Blish, A.E van Gogt, Paul Anderson, and of course John Wyndham to name just a few other the authors I still remember fondly from my childhood and youth.
I subscribed to a short lived monthly magazine published by New English Library called Science Fiction Monthly that survived for three years. They were similar to an A3 size magazine, with up to 10 double paged posters of the book covers from all of the big Sci Fi books of the time. I plastered my large student room with many of those posters and my room even featured in the universities year book in the section that covered student accommodation because I was also a very tidy student and my room looked pretty amazing with the walls covered from floor to ceiling with some amazing posters as well as my favorite potted plants ( a gorgeous Jasmine that reached the ceiling, several ivy plants as well as a large Yukka and a large Umbrella plant that also reached the ceiling; both of the latter I still have 40+ years later, but my student room is no more as it was demolished to make way for a gambling casino.
pets happily Hi, Mr. Whiterabbit.
