I just read Anubis Gates (by Tim Powers) and King Solomon's Mines (Henry Rider Haggard).
Anubis Gates was a really great book and it surprised me actually how Powers managed to make everyhing in the story seem plausible. By mixing his fictious storyline with real historic facts and persons, the story just gets a lot more believable while some of the things that happen in the book are completely impossible.
I just bought a couple of other books by Powers and I'm certainly expecting great stuff after reading On Stranger Tides and Anubis Gates!
