If you aren't familiar with Kara, here is a blurb from world magazine:
Kara Tippetts and her husband, Jason, have a lot going for them, including four beautiful children and a thriving new church that Jason started and serves as pastor. But soon after moving to Colorado Springs, Colo., to start that church, Tippets discovered she had breast cancer. Despite aggressive treatment, the cancer spread throughout her body.
Kara describes herself as a terrible sick person. She hates being sick, so it might have been easy for her to retreat into self-pity. Instead, she started blogging about her experiences with a remarkable transparency that immediately won her as many as 20,000 daily page views on her blog, Mundane Faithfulness. A publisher soon discovered the blog and the result is her first book, The Hardest Peace: Expecting Grace in the Midst of Life’s Hard.
Heidi again. I bought her book. I've yet to read it. Her blog posts make me cry, I'm afraid to open her book. When Kara writes, her heart pours out. You can see that open heart in pictures of her. Even in pain, her smile is wide and opening.
