In the difficult year that follows, additional failed fertility treatments threaten her new marriage and her mental state. By some saving grace, she becomes pregnant naturally, but her son is diagnosed with potentially terminal kidney complications. Ultimately, Nadine learns that in a unpredictable life, the only thing she can be sure of is the healing power of hope' -- From back cover.
