Sundance — Richard S. Wheeler

Along the Oregon Trail, a war party of Lakota Sioux rob Con Brann of all that he holds dear--his horses and, more devastatingly his lovely daughter Hester.  Only Mister Skye, guide and scout to the Great Plains, can help Brann now.
 
Meanwhile the Sioux, 10,000 strong, gather to celebrate their ancient Sun Dance ritual, praying for vengeance upon their enemies, including Skye.
 
Skye, honor-bound to rescue the young girl, must infiltrate their sacred ceremony…even though discovery means horrible death.
