I am a big lover of epic sci-fi / fantasy, and have been totally rapt by the likes of Greg Bear (Eon, Eternity) and Clive barker (Imajica, Weaveworld) and David Eddings. I am now reading Greg Bear's Darwin's Radio, and will then read it's sequel, but am in a bit of a dilemma as to what to read next. I love the hard science slant in DR (genetics, evolution) but I also like the epic factor like in Bear's Eon and Eternity. Does anyone know of any books that are epic and contain the hard science element, preferably books that are part of a series? Any help would be appreciated...
