Wild Honey by Fern Michaels

Sloan MacAllister was the loyal white brother of a mighty Seminole chief -- an American renegade pledged to save a proud tribe from a cruel general's ruthlessness during the Indian Wars. Deep in the lush Florida wilderness, he encountered a savage golden-haired beauty, raised by the Indians since childhood. A gift to him from the grateful chief Osceola, lovely Chala joined Sloan in the battle for the Seminoles' freedom. She was a fierce warrior in a noble cause...a woman whose love defied the treacheries of fate...and a passionate companion as sweet and untamed as "Wild Honey."
