Cindy Woodsmall Sisters of the Quilt series is one of my favorites. You can now get all three books in one volume - When the Heart Cries, When the Morning Comes, When the Soul Mends. I have yet to read The Hope of Refuge and Bridge of Peace because I want both in my possession before I start reading...don't want to be left hanging waiting for the second book.
I've downloaded these on Kindle for PC/Android.
Marta Perry "In Plain Sight"
Suzanne Woods Fisher Lancaster County Secrets series. I've only read book 1: "The Choice", but have the others on my wish list
Barbara Cameron Quilts of Lancaster Series, I read book 1: "A Time to Love", and book 2 was just released in March
