A favorite book from my childhood is Laura Ingalls Wilder's The Long Winter. My family moved all over the US when I was growing up but my grandparents and great grandparents were pioneers in South Dakota. That book gave me such a sense of identity that I went on to read every one in our litttle mobile library that she wrote. Many years later, I read them to my children during an especially difficult winter. Their simplicity and and good will rang true all those years later.
As an adult, The Color Purple helped me to understand the deep power of love especially in the face of great trials and injustices. Two books I recently finished before your wonderful book continue to haunt me and cause me to rethink my assumptions. The are The Book Thief and Mornings in Jenin. Others have mentioned the difficulty of chosing which books meant the most, and I couldn't agree more. The amazing thing to me is that so often the perfect book finds its way to my hands at the perfect time. Your book helped me following the death of a special aunt. Love of family and books shine in every chapter.
