Turquoise Guardian

Her Warrior Protector 

Carter
Bear Den is a proud Apache of the Turquoise Canyon Reservation. The
former US Marine is a member of the Turquoise Guardians working to
protect his people and their land. When he discovers a grisly mass
shooting at the Lilac Copper Mine, Carter's one thought is to find Amber
Kitcheyan. 

After breaking her engagement to Carter and
relinquishing her membership with the reservation, Amber found work at
the mine. Now she is the sole survivor of the shooting–at best a
witness, at worst a suspect. But Carter swears to protect the only woman
he has ever loved, even if it means losing everything else.
