In the ancient Kingdom of Kaffa, Princess Mersabel mourns the loss of her brother in battle. Her father, the King, undeterred by his loss, prepares for a fresh war. Meanwhile, the Princess's mother is desperate to secure her position within the kingdom and dreams of marrying the princess to a prominent man. But the princess is not in love. Great excitement breaks forth in the court as a caravan of merchants arrives at the palace, bringing the King an English scholar. They claim that he is an expert in making rifles. The King purchases the Englishman with eight castrated slaves. Powerful and consequential people demand a lot from the unfortunate man. Without the help of the young princess, his life is in great peril...

Read a Forward to PRINCESS MERSABEL by the late Professor Richard Pankhurst (OBE) -- a leading scholar on Ethiopian History and the son of Sylvia Pankhurst here: FORWARD TO PRINCESS MERSABEL

Many young people and their families sacrifice a lot for the sake of pursuing a good education. Some leave their loved ones and dear friends behind to cross boundaries and even oceans, besides footing the bill for college education. But what if, in spite of apparent academic success, and with it improved career prospects, you still wonder where your life is headed? What if your new reality doesn't match your expectations, and instead of mere homesickness, you succumb to loneliness, instead of fulfilling your dreams, you flounder for want of direction and wholeness? ERMIAS is a story about a young African student who comes to Europe in pursuit of a higher education, but along the way struggles to determine what differentiates his primary desire from all other desires, including the desire to fall in love with a married woman...

Danny is a sickly and frail boy of twelve. Fed up of leading a life full of worry and anxiety, he stows away to a border town to visit his father. On the fourth night with his father, he accidentally overhears his father confessing to his adoptive sister that Danny will soon die. Stunned by this revelation, he is unable to sleep that night. He sneaks out of the house and spends the night on a nearby hilltop. Very early in the morning, he witnesses an enemy jet bombing his father's living quarters. Shortly thereafter he meets Samuel, who persuades him to escape into the wilderness with him as the country is on the brink of war. They determine to cross the wilderness on foot in the hope of reaching the next city, which is about three hundred kilometers away. However, the boys are forced to interrupt their journey frequently on account of Danny's repeated and violent coughing fits. Samuel, who gradually realizes that Danny's primary illness is psychological rather than physical, has to first coax Danny into forgiving the past as well as the present in order to redeem their future.

What do some of the brightest and most original scientists and writers believed about the meaning and purpose of human strive?

Very few twenty-century scientists made as a lasting influence on modern society as Albert Einstein and Sigmund Freud. Physicists routinely use the theories Einstein developed a century ago to analyse and comprehend cosmological and quantum phenomena. Similarly, some of the vital models contemporary psychologists routinely apply in order to explain psychosexual developments and human psyches are credited to Freud. Perhaps less known to the general public is the magnitude of influence Fyodor Dostoevsky and Leo Tolstoy had on both Einstein and Freud. Einstein once declared: "Dostoevsky gives me more than any scientist, more than Gauss." Freud too ranked Dostoevsky's The Brothers Karamazov alongside the works of Shakespeare in terms of its literary significance. Tolstoy had likewise influenced Einstein and Freud.

Two of the subjects, in which they held a common interested with comparable magnitude, were God and the purpose of human life. All of them, without exception, had passionately been occupied by and written and talked extensively about these subjects. The purpose of this book is to closely examine the beliefs of the quartet based on the books and articles they produced over a span of many years. The author has made a great effort to make their views as comprehensible as possible for the general reader without diluting or oversimplifying them.

As of 25 November 2020, THE REASON FOR LIFE was #5 on AMAZON GERMANY's BESTSELLER RANK under Religious Philosophy category.
