Lucy Carpenter and her husband, Jonah, are happily married and planning to have a baby. When she becomes pregnant, Lucy spends her evenings knitting baby clothes. She has a pregnancy book she reads to discover how her baby is developing week by week, and imagines how happy their lives will be once their baby is born. Her heart is broken when she has an miscarriage, but they are determined to try again. Sorrow strikes a second time when she has another miscarriage. As Lucy struggles to deal with the pain of her losses, she must also adjust to the arrival of her teenaged step-daughter, Camille. Lucy hopes to build a relationship with her, but instead finds herself feeling like an outsider in her home. Envious of the relationship Jonah has with his daughter and fearful that she will never be able to have the baby she desperately longs for, Lucy begins to resent Camille’s presence. The rocky relationship she has with Camille causes a rift to form between Lucy and Jonah, and Lucy is less than thrilled when Camille announces she’s staying. A shocking turn of events brings about a situation that will either bring them together, finally, as a family… or tear them apart.
