A Harvard-trained neurosurgeon's minute-by-minute account of his own near-death experience - and what he discovered in the heavenly realm beyond life.

On November 10, 2008, Dr. Eben Alexander was driven into coma by a disease so lethal that only 1 in 10,000,000 survive. Seven days later, he awakened with memories of a fantastic odyssey deep into another realm that were more real than this earthly one - memories that included meeting a deceased birth sister he had never known existed. Dr. Alexander deployed all his knowledge as a scientist to find out whether his mind could have played a trick on him. In its shutdown state, there was no way it could have functioned at all. That left only one conclusion: that we are conscious in spite of our brains - that, in fact, consciousness is at the root of all existence.

The evidence supporting Dr. Alexander's experience transformed him into a believer in God's unconditional love and brought reconciliation to his family - and will upend our ideas about human consciousness and spirituality.
