On the morning of her wedding, veterinarian Andrea Moore knows she's making a mistake. When she learns she's won a buffalo ranch, she runs off to North Dakota but finds herself in the middle of what could be an even bigger mistake. The ranch she's won is not only home to a herd of bison, but also run by a man who can't hide his hostility. Foreman Mike Winterhawk worked long and hard to buy the ranch himself, only to have it handed over to some contest winner. His focus needs to be on why the bison can't bear calves instead of teaching this city slicker in ugly green cowboy boots how to run a ranch. He can only hope she'll quickly realize she's out of her league and hightail it back to Seattle. So, why is he so attracted to this intruder, and why does he feel she might be the one who can help him turn White Thunder Ranch around?
