Stumbled across a new James Van Praagh book, Growing Up in Heaven: The Eternal Connection Between Parent and Child.
Besides giving reasons why the young die, in this book Van Praagh goes into quite a bit of depth about the evolution and journey of the soul. I'd recommend reading the book if only for that reason.
It is amazing how contact with the dead gives so much life.
For those of you who don't know, James Van Praagh is a medium and has been doing this for a very long time. http://www.vanpraagh.com/
