In 1921, Paul Amadeus Dienach, a Swiss-Austrian teacher with fragile health, falls into a one-year-long coma. During this time, his consciousness slides into the future and enters the body of another man, Andreas Northam, in the year 3906 A.D. When Dienach awakens from his coma, he finds himself back in 1922. Knowing that he doesn't have much time left, he writes a diary, recording whatever he could remember from his amazing experience. Without any close friends and relatives to entrust, he doesn't say a word to anyone out of fear of being branded a lunatic. Before he dies, he hands his diary to his favourite student, George Papachatzis, Mr. Papachatzis translates the diary slowly, realizing that what his teacher describes in detail is an account of time travel and the knowledge he has gained about mankind's history in the forthcoming centuries--from the nightmare of "the Number" (Overpopulation) and World Wars up until the 23rd century, to the world-changing globalisation, the radical new administration system, the colony on Mars and the next human evolutionary stage, Homo Occidentalis Novus.
