Letters to Zane is a heartfelt story of a woman who finds herself about to become a single mother and unknowingly about to fight for her life and the life of her unborn child. She learns she has Hyperemesis Gravidarum, and must face her own mortality. Raynie Andrewsen originally wrote Letters to Zane as a journal to her unborn son, so that he would know how much he was wanted and loved. She quickly realized that her story could help other mothers struggling with Hyperemesis Gravidarum. She believes that it will give them hope when there seems to be none.
