Down in the Bottomlands (and Other Places)

More about the book

In our world, the Mediterranean basin has dried up several times, only to refill again. If it hadn't, that sea bottom would have become the most savage desert on earth. But in his world, that's just the way that mild-mannered Radnal vez Krobir likes it. When the enemies of his kingdom try to shake down the Barrier Mountains and let the Atlantic in, it's up to him to stop them - or else drown along with everything he holds dear.
