Rex Donnar sets out to buy a stallion, but the trail leads him into a struggle that will change his life. His brother Richard is dead, the Rocking D is in danger, and powerful men have their own plans for the land he has left behind. As Rex searches for answers, stolen horses and a mysterious map draw him deeper into the secrets of Shadow Valley. Annie Stoddard has a place in his heart, but her father stands between Rex and the truth. With loyalties divided and danger closing in, Rex must decide whom he can trust—and what he is willing to risk for the people and the life he hopes to protect. Against the rugged landscape of Texas, Secrets of Shadow Valley: The Beginning brings together ranch life, romance, and a fight for justice in a country where a man's word can be his strongest bond—or his deadliest mistake.
