Just finished Lost Boy Lost Girl by Peter Straub. It's the story of a writer who's sister in law suicided, and her son (actually the writer's nephew) disappeared a few days after, while he was obsessed by an abandonned house of the neighborhood. It was nice to read and well written, but I found that the story was lacking a bit of originality and was not absorbing as I would have expected. That book has gotten the Bram Stoker prize as best fantasy novel; personally I would say it's rather a thriller with a bit of paranormal rather than fantasy, though. Yesterday I began Red Mars by Kim Stanley Robinson.
