Don't Fence Me In - The Campbell Cousins, #1

Cameron Ross lives a double life. Most people recognize him as the world's hottest leading man--the new Cary Grant. Those people would never recognize him as the man who wakes at the Flying V Ranch in Montana the morning after an epic drunk. That man is a scruffy horseman who seems to fit seamlessly in the mountain valley his ranch inhabits. That man's name is Noah Campbell. Cameron is a myth. Noah is the real man who bought a ranch in order to remind himself of that fact.
What's also real is his ranch manager, Dulcy McCann, who has risked everything to protect her position and her precocious sprite of a daughter, Hannah. Noah knows he should not develop an attachment to either of them. Dulcy thinks he's Noah, a businessman. Her world is Montana, not the fishbowl of notoriety he inhabits. As for Dulcy, she has enough on her hands balancing the rigors of the ranch and the much tougher job of raising her daughter.
The last thing she needs in her life is a new boss so compelling he's interfering with both. Especially when they're threatened by secrets Dulcy can't share.
