The Second Vow (The Mounties #2)
Kathryn Fox

As a dedicated member of the Northwest Mounted Police, Irishman Braden Flynn had only one mission: escort the Sioux as they fled across the U.S. border after the battle of Little Big Horn. And yet he could not help but be distracted by Dancing Bird, the stunningly beautiful niece of Sitting Bull, whose spirit and loyalty to her beleaguered people touched his heart as never before. Though a fierce desire smoldered between them, Braden knew that Dancing Bird was reluctant to trust a white man. Now, amidst the clash of two governments and murderous upheavals, nothing--neither grueling hardship nor mortal danger--can keep him from winning her trust...and her love.
