Bastion. A solitary fortress isolated in an endless sea. A city of secrets where the elite dominate with an iron fist and ambition ends at the city walls. Ordinarily the city is surrounded by water but one day a month when the moon is at its highest, the water recedes and uncovers the causeways linking the city to the outer towers. This is Moon-day, the time when the trades bring their specialties to market and the whole Citadel enjoy the celebrations the festival brings, so when the city's stargazer predicts the water level will drop even further, nobody takes any notice. Soon enough and despite the people's indifference, the predictions are proved correct and as the sea falls, it reveals secrets that have never been known before. Secrets that are at first exciting... then disturbing... and ultimately... terrifying.

AD 1270: Antioch has fallen, Tripoli is under siege, and Sultan Baibaars targets his Mamluk hoards against Krak des Chevalier, the Crusaders' greatest stronghold in Syria. The Holy Land is in turmoil and desperately awaits the arrival of Edward Longshanks and his relieving army of French and English Crusaders. This is a time of brutality, an age of chivalry. A time of strong men with stronger hearts, an era with no place for the weak. Yet a thousand miles away, a 14-year-old boy learns a disturbing secret that drives him on a Crusade of his own. A quest to avenge his family, save his brother, and in the process recover the holiest relic in the history of Christendom.
