India Summers is a librarian and a talented historian, so when a stranger asks her opinion on an ancient coin she is happy to oblige, but when the same man is murdered less than an hour later, it soon becomes apparent that there is far more to the situation than meets the eye. Recognising her unique talents for historical reference, she is quickly recruited by Brandon Walker, a security service intelligence officer investigating the strange disappearance of a very special young girl.

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.

1081. William's bloody conquest is over and Britain is under Norman rule. But one bastion of resistance remains: Wales. A divided land where brother fights brother and kings battle for power. The English use this to further their own ends, and while one king is tempted by an offer he cannot resist, the others wage war over long-forgotten feuds.

25 BC. Titus Cervianus is no ordinary soldier. A former surgeon from the city of Ancyra, he's now a capsarius—a combat medic. Cervianus is a pragmatist, a scientist and truly unpopular with his legion. The Twenty Second Deiotariana have been sent to deal with uprisings and chaos in Egypt. Yet the Twenty Second is no ordinary legion either. Founded as the private royal army of one of Rome's most devoted allies, the king of Galatia, their ways are not the same as the other legions, a factor that sets them apart and causes friction with their fellow soldiers. 

AD 1045. Godwin of Wessex, one of the most powerful earls in the country, prepares for the marriage of his daughter to King Edward of England. The mood is jubilant, his family's relationship with the Crown secured through matrimony. But one man seeks to undermine him at every opportunity.
