Brown's book is a very interesting memoir of his astronomical career and discoveries of several dwarf planets. It was a bit lighter on the science than I would have liked, and his somewhat sparse details about the actual astronomy behind some of his work left me a bit disappointed. For what it is, though, a recollection of his life and how that ties into the changes in our view of the solar system, How I Killed Pluto is a fun read and, if nothing else, a non-media voice from inside a fascinating controversy.
