Anne Du Lac and the King's Birthright

"So, all we have to do is steal from a thief, find a mythical sword, and make a king, right?"

EXCALIBUR, King Arthur's mighty sword, has the power to make or break pretenders to the throne of England. But it has been missing for more than eight centuries along with a great treasure.
A small group of monks have kept the location hidden and only one who solves the puzzle of three stones will know how to reach the sword.
Royal succession is in the wind, but time is running out as Anne tries to solve the mystery of the three clues that lead to the sword's resting place.
The fate of a kingdom hangs in the balance . . .
