I recently finished reading Though My Heart is Torn by Joanne Bischof. This is a wonderful second book in the Cadence of Grace series.
Lonnie and Gideon's journey continues, filled with heartache and characters wrestling with whys and regrets. While heartbreaking, this story has its hopeful moments, and is filled with the tenderness and realness that Joanne Bischof is known for. The rugged backdrop of the Blue Ridge Mountains is beautifully portrayed. I can easily imagine myself there, and the struggles of life in the mountains.
I don't want to give away the story, so I won't say more. Just know that I highly, highly recommend the entire series (I just started reading book three!) and any books written by Joanne.
