I'm a huge fan of Issac Asimov and Arthur C Clarke and they both have an incredible portfolio of work. Asmiov's Robot stories are great and for Clarke you could go for the Space Odyssey books or the Rama books.

I'm currently reading ORA:CLE by Kevin O'Donnell Jr which is an interesting old sci-fi book which seems excellent.


For Fantasy I would recommend Ursula Le Guin's Earthsea books which are a classic collection, and Susan Cooper's Dark is Rising Series are another excellent up to date fantasy romp.


If you want some Science-Fact I'd recommend Hyperspace by Michio Kaku which is an incredible journey into multi-dimensional science.
