I was given a copy of Baltimore a few years ago for my birthday, and there it sat on the shelf until it finally reached the front of my book queue. It's really an extraordinary work, written and illustrated by Hellboy's creator Mike Mignola along with Christopher Golden. The story creates great atmosphere, as the protagonists travel in an age of general decay, despair, and lethargy as a terrible plague sweeps Europe. Only, the "plague" may have a more sinister origin than a mere virus. I don't want to talk much more about the plot without giving stuff away, so I'll simply say it works great for a couple of nights' bedtime reading if one's in the mood for something spooky.
