Ties That Bind — C.J. Darlington

When Brynn Taylor is released from prison she decides to fulfill her mother's dying wish and find her father, a man she's never met. Armed with a bus ticket, a backpack, and her grandfather's gun, her search leads her to Elk Valley, Colorado. She's prepared to face the man who broke her mother's heart, but when she discovers she has two sisters who have no idea she exists, her plan begins to unravel. Too ashamed of her record, she can't bring herself to reveal her identity to her sisters until she gets her life together. Instead, she tries to fit into their busy lives of horse training and bookselling, hoping they won't suspect who she really is. But an unexpected death sends Brynn into a tailspin. How can she win her sisters' love if she can't even keep her former drug addiction under control? Will her past catch up with her before she gathers enough courage to tell her sisters the truth?
