And here's the blurb from the publisher:
Two men who hate each other. One impossible mission. A legend in the making.
Hadrian, a warrior with nothing to fight for is paired with a thieving assassin, Royce, with nothing to lose. Together they must steal a treasure that no one can reach. The Crown Tower is the impregnable remains of the grandest fortress ever built and home to the realm’s most prized possessions. But it isn’t gold or jewels that the old wizard is after, and if he can just keep them from killing each other, they just might do it.
August of 2013 can't get here soon enough.
