First of all, I'm thrilled you enjoyed Love's Rescue. Yes, there will be a third book in the Keys of Promise series. It doesn't have a title yet, but the story is well underway. Thank you for writing!
I'm currently working on a new series with Love Inspired Historical, BOOM TOWN BRIDES. Set in an 1870s lumbering town, the story follows a woman who answers a mail-order bride advertisement in person only to find two other women vying for the same groom.
