Dark Shadow's Revenge

In younger days Joshua Logan had fought Apaches in the mountains bordering Texas and Mexico. Because he appeared in places he could not be, he had become known as Dark Shadow, or in Spanish, Sombra Preta.
Logan battled so ferociously that even the best of the Apache fighters who had hidden at their secret spring fell before his deadly rifle.
Now Logan was back, this time seeking the deaths of border bandits that had savaged his village.
Led by a renegade known as Punto Negra, named for the massive gunpowder scar on his face, the outlaw band numbered twenty-one experienced killers. Logan was alone.
Readers have described Dark Shadow as the best western novel they have ever read. You might feel the same.
