Way too many to mention! I loved magic and space ships and dragons and wizards and knights and aliens and ghosts and weirdness. So everything by CS Lewis (Narnia and SciFi), Elizabeth Beresford, John Christopher (who did WAY more than just the Tripods trilogy), Gordon R Dickson (Time Storm! Wow!), Philip K Dick, Isaac Asimov, Larry Niven, Piers Anthony (especially the Incarnations of Immortality series), and so many, many others. But also animals and things; so I loved Gerald Durrell and Farley Mowat, too. Plus I was always a sucker for those science books that looked to the future and had things like fields of cows in round skyscrapers!
