About 12 years ago I read a book about a new form of computing (quantum computer) and the ability to use these to communicate with the soul. I cannot for the life of me remember the title, but I can remember aspects.
In the book there is a religious opposition to the use of the computers, but ultimately the computer gets used to communicate with a dead person's soul and witness the 'afterlife'... I only remember sketchy parts but I am sure at the end the person whose soul links with the computer sees 'hell' or 'the devil'... or something like that... I also think the name of The book has the word 'light' in it..
Please please please can you help me identify the book?
