The Fibonacci Confessions is a story of discovery, adventure, romance, and betrayal. This exciting novel presents the intimately personal letters of Leonardo Pisano (also known as Fibonacci), mathematician, scholar, and traveller, looking back over a lifetime at the follies of his youth, travel in North Africa, Egypt, the disasters of various amorous affairs, and his endless pursuit of the 'numbers' in a quest which leads to both glorious and tragic consequences. Fibonacci, telling his own tragic story, keeps few secrets hidden as he passionately pursues his destiny in a medieval world where there are many hazards and few rewards. His story begins in innocence and ends in calamity, as step by step he indulges in the flaws which lead to his downfall. From every experience Fibonacci learns new lessons, but somehow he always commits the same errors with the inevitable consequences.

This beautifully crafted historical novel by Graham Wade recounts the meteoritic rise of an orphaned peasant boy from Turkey to the exalted position of confidant to the Emperor of Russia, the insane son of Catherine the Great. The Emperor's Barber is a riveting story of adventure, romance, and retribution in which the author presents the memoirs of Kutaissov, the Turkish barber who became a trusted adviser to the Tsar in the eighteenth century. As Kutaissov relates his intimate memoirs the many facets of his nature are revealed, as well as the development of a perilous relationship with a tsar usually considered as either mentally unstable or (at his worst) totally deranged. The historically accurate and witty writing describes court life at the turn of the nineteenth century, using real-life characters and a great imagination to interpret the historic events that led to the demise of Tsar Paul 1.
