Speaker for the Dead

This book is the sequel to the "Ender's Game" I read last week.  It also won a Hugo so I have not strayed from following this award's path. However I am of a mind to go find the other eight or so volumes that appeared after these two.  In this case they must be read in order. There are too many references back to the first volume even though the story is set 3000 yar into the future from the first volumes timeline.  For a starter some of the characters are still alive due to the physics of light speed space travel.  Ender's job after this time is mainly giving eulogies and trying to redeem previous situations by having unlikely aliens living together on one planet.  I notice this story has been illustrated in a series of comic books by Marvel !!
