The Bardo is the interval that everyone goes through when they die and are reborn. This is an excellent book of 130 pages on this subject which is based on the commentary on this complex subject  by Chokyi Wangchuk who was the sixth Shamar Rinpoche.

This book gives and explanation in a very readable form of the four bardo and what one can do to prepare for them.

There is also a section of this website which has many other books on the bardo available.
