Flint

He came out of Malpais, the terrible volcanic badlands where nothing can live, riding a giant red stallion no other man could put a hand to. His boots were polished, his speech was gentle, but his guns were quick and smooth as silk. He shot first and talked later.

He left the West at the age of seventeen, leaving behind a rootless past and a bloody trail of violence. In the East he became one of the wealthiest financiers in America--and one of the most feared and hated.
Now, suffering from incurable cancer, he has come back to New Mexico to die alone. But when an all-out range war erupts, Flint chooses to help Nancy Kerrigan, a local rancher. A cold-eyed speculator is setting up the land swindle of a lifetime, and Buckdun, a notorious assassin, is there to back his play.
Flint alone can help Nancy save her ranch...with his cash, his connections--and his gun. He still has his legendary will to fight. All he needs is time, and that's fast running out....
