I read Tower of Glass with my Beloved, and it took a long time, as the baby seldom lets us read for very long at a time any more. Borrowing heavily from themes in Brave New World, this book tells of a story where all the menial labor is done by androids, of the egotistical man who invented them, and of the religion that they form around him.

Fascinating, and very thought provoking, particularly if you accept the notion that we could one day create cloned humans.

This was recommended by @stevestoneky, one morning at the bus stop.
