A raw, authentic glimpse into the lives of young parents as they navigate childhood cancer, this diary-style story is filled with the pain of loss. But, as the title reveals, it is also filled with faith, laughter, determination and optimism as a small child battles brain cancer. Hayley and Justin are young parents devoted to their four-year-old daughter, Kallie, as she fights battles no one should have to fight, especially a child. They are equally devoted to her younger sister, Kora, as she learns as a toddler, about a disease too difficult for anyone to comprehend.
