The Tournament — Matthew Reilly

The year is 1546, and Suleiman the Magnificent, the feared Sultan of the Ottoman Empire, issues an invitation to every king in Europe: You are invited to send your finest player to compete in a chess tournament to determine the champion of the known world.

Thousands converge on Constantinople, including the English court's champion and his guide, the esteemed scholar Roger Ascham. Seeing a chance to enlighten the mind of a student, Ascham brings along Elizabeth Tudor, a brilliant young woman not yet consumed by royal duties in Henry VIII's court.

Yet on the opening night of the tournament, a powerful guest of the Sultan is murdered. Soon, barbaric deaths, diplomatic corruption, and unimaginable depravity -- sexual and otherwise -- unfold before Elizabeth's and Ascham's eyes. The pair soon realizes that the real chess game is being played within the court itself…and its most treacherous element is that a stranger in a strange land is only as safe as her host is gracious.
