Morning Comes Softly by Debbie Macomber

A shy Louisiana librarian, Mary Warner fears she’ll always be alone—so she answers a personals ad from a rancher in Montana. Never before has she done anything so reckless, casting the only life she knows aside to travel to a strange place and marry a man she’s never met. But something about this man calls to her—and she knows this may be her very last chance at happiness.
Tragedy made Travis Thompson the guardian of three orphaned children—and determination leads him to do whatever it takes to keep the kids out of foster homes. When he decides to take a long shot on a personals ad, the results are surprising, and before he knows it, he has agreed to marry a mysterious Southern woman sight unseen.
It could be the mistake of a lifetime. But Mary Warner may be exactly what this broken family needs. And with a little faith, a little trust, and a lot of love, two lonely hearts might just discover the true meaning of miracles.
