I've always been fascinated by maps. When I was young, I would pull out the map that came with each month's National Geographic Magazine, and add it to a box hidden in my closet, for adventures some day far in the future. There are maps that show the things that put us in a specific geography -- roads, rivers, continents -- and there are the other kind of maps, the ones that guide us through the intangible ways we inhabit our world. You Are Here collects more than 100 maps of the imagination, and the journeys they chart are extraordinary.
