His Pledge to Obey. a Silver Star Ranch Romance, #4

When Brigadear Silver meets a wounded warrior whose injuries leave him feeling all washed up, she'll need to prove she's grown up enough to get him on bended knee. Brigadear Silver might be the youngest of the five Silver girls, but it's clear she's the smartest. Well, clear to everyone except her sisters, who still treat her like a baby. When Brig sets her sights on Jackson Michaels, she longs for him to see her as she is-a fully grown woman.
But if her sisters don't stop treating her like an infant, she's liable to throw a tantrum. Jackson Michaels thinks he's past his prime. Booted out of the military with a knee injury, he feels useful working the ranch of his former commander. Entering into a marriage of convenience with one of the late general's daughters to meet the requirements of the man's will is no problem. But he's sure the gazes he keeps sneaking at Brig, who's far too young for him, are not a part of the general's last wishes. The closer he gets to her, the more he realizes she is the woman he needs.
But with his body so battered and bruised, his doubts are even louder than his aches and pains. And if Brig can't get Jackson to commit to their love in sickness and health, their relationship will never stand the test of time. Find out if love can truly heal all wounds in this light-hearted, sweet romance of convenient arrangements that unfold into lasting love. His Pledge to Obey is the fourth in a series of marriage of convenience tales featuring Wounded Warriors who are healed with the power of love.
