1429: A city under siege. A future in the balance.

When another glitch in time threatens the fabric of history, eighteen-year-old Dan Renfrew and his partner Sam Cahill jump into the past again. They land in medieval France, just before Joan of Arc's miraculous lifting of the Siege of Orléans. But this is a world dominated by religious intolerance and fear, where one wrong step could lead to torture or death at the hands of Catholic priests. And when accusations begin to surface, Dan and Sam find themselves in an impossible race against time. To survive--and keep history intact--they must outwit fanatics, dodge soldiers, and endure the chaos of 1429. One wrong move could cost them their lives . . . and rewrite the future forever.
