Fortune hunter's hero

When Buck Wyatt and his sisters inherit Broken Arrow Ranch, it comes with a catch: One of them has to be on the premises at all times for one year, or they'll lose it. So Buck counts on setting up stakes. What he doesn't count on is lovely fortune hunter Rainey Brewster. He soon realizes the woman is telling the truth about a hidden gold mine--and that his interest in her goes beyond professional. Yet as their search for gold--and their passion for each other--intensifies, it's clear someone wants them off the land--and is willing to kill for it.
