The Endurance of Moses Wilson. The Laredo Series, #2

Moses Wilson left Kentucky with a mission to save his brother, Boone, from the hangman's noose and succeeded just before all hope was lost. Almost five years later, he's made his home in Texas, working on the ranch where Boone is top hand. When he meets ranch owner Liam Rafferty's sister-in-law, he's smitten with her blonde beauty and sassy manner. Ranch life in the 1870s isn't easy, though. After enduring mishaps, including a fall from a horse and a sprained ankle, nearly freezing to death, and a near-fatal bout of pneumonia, he also has problems courting Mattie.
Although she's willing, her prosperous German family isn't, and their efforts to force her into marriage with a wealthy banker cause trouble. Moses must endure much to have the life he wants on the ranch and marry the woman of his dreams.
