Wanna be thinking over the hols? Perhaps a history of space (that is to say, gaps) and what the Internet might mean for our conception of heaven might be the go. $16.
Seems like Oliver Sacks (quoted on the cover) like the ending more than this reviewer on Goodreads:
"This book dies in the arse a bit - the end really isn't nearly as interesting as the start, but the start is really, really interesting."
