Wanting to prove she can be a strong, self-sufficient woman of the twenty-first century, Spring Ryan decides to spend her thirtieth birthday hiking the Appalachian Trail through the Smoky Mountains. Her third day in, she's ready to give up and crawl back into the small box she's lived in for a dozen years when a pair of Irish Wolfhounds cross her path. When they turn into gorgeous identical twins, she is amazed, especially when they claim she is their mate. Adam and Brock Sullivan are the oldest of four sets of twins living in the hidden valley of Sanctuary. They had just about given up on ever finding their mate when they come across her just two miles from their home. Can Spring make a life for herself in Sanctuary? Will her family accept her decision to live with and love both men?
