i read a lot of hard sci-fi, mostly whatever is on the 'new book rack' at my library that looks interesting. a couple of my favorite authors, that i'll go out of the way to find new work from if it's not on the rack, are Charles Stross, Peter F. Hamilton & Peter Watts.
recently i read 'Redemption in Indigo' by Karen Lord, and adored it, then read all the rest of her work i could get my hands on. not sci-fi, mostly, more neo-African folklore, but worth reading.
i don't generally get much from 'devotional' books by Christian authors; i'd rather listen to expository preaching, which i do a lot of. maybe it burns me out on reading theology books? for some reason i find listening to people's opinions on scripture more palatable than reading hundreds of pages of similar material.
