Martha Jean Flynn opens her ranch door to the enigmatic Ridge Longtree, a half‑Native‑American wanderer turned reluctant rescuer after her father's murder and sister’s abduction by Apaches. Together, they journey up jagged mountains, where danger, sorrow, and a deepening romance ignite.

In colonial New Mexico, Anna Alexander survives a self‑defense shooting and seeks refuge, only to find love and danger when she saves half‑breed bounty hunter Storme Warwick.

Auburn-haired Morning Star had nearly forgotten that she was the white man's captive. Ever since the defeat of Geronimo the beautiful Apache half-breed had lived in deceptive freedom at the Indian school. But her dreams of becoming a teacher were shattered when she learned that she was to be taken to a barren reservation in faraway Oklahoma. Her only hope of escape was to elude the handsome Cavalry officer who was her official escort, but when Lieutenant Travis Wade captured her in his embrace, an unexpected thrill ran through her body. She forgot about fleeing as his strong arms pressed her silken curves against his well-muscled chest and his lips conquered hers in a kiss of fierce possession. Travis Wade sympathized with the Indians, and he didn't like escorting them back to the reservation, but orders were orders. The job was going smoothly until he caught the feisty half-breed minx trying to run away. He only meant to hold her tightly until the train was in motion, but the touch of her satiny skin enflamed his senses and the flashing fire in her steely blue eyes dared him to try and tame her. And as they traveled westward toward Fort Sill, Travis vowed to hold the beguiling Morning Star in his arms forever in a celebration of the fiery passion and wild pleasures of his newly captured Apache Tigress.
