Scholar and Priestess of Ptolemy for the mysterious Order of Alexander, Lady Irisi of Alexandria searches for the lost body of Alexander the Great. Closeted in her home, surrounded by her manuscripts and scrolls, she knows much about languages and lost teachings but nothing of men and war. Sir Ronan Wyvill is the bastard son of a lord, a mercenary who followed the Crusades to Egypt only to have his men slaughtered and abandoned to the whims of Fate. He finds a safe haven in the home of Lady Irisi, who intrigues him with her beauty and seduces him with her otherworldly wisdom. When Ronan learns that he has the key to unlock the mystery that Irisi has been trying to solve, he offers his services as her bodyguard so as not to let the innocent temptress go on her quest alone. From the streets of once mighty Alexandria to the splendors of medieval Venice and finally the ruins of ancient Egypt, Irisi and Ronan engage in a race against a foe as old as Alexander himself. A foe that will stop at nothing to gain the prize first and bury them in Egypt's burning sands forever.
