Opal (Dakotah Treasures Book #3) [EPUB ebook] 

Book 3 in the bestselling Dakotah Treasures series. Dove House has burned to the ground, Ruby and Rand have married, and now Rand’s ranch is home for them all. Ruby’s younger sister, Opal, is taking to ranch life like a hummingbird to sugar water. She can outshoot, outride, and work as hard as any cowboy on the place. Ranching has clearly stolen her heart. When a young minister arrives from the East, he is amazed to find himself falling in love with Opal, even though she is not a woman anyone would think of as a pastor’s wife. But when God takes hold of a heart, He can work amazing miracles, and Jacob Chandler just might be the one to eventually woo her away from the ranch.
