In her first year of motherhood after an unplanned pregnancy, Cate is constantly exhausted, spiraling into self-doubt and postpartum anxiety. Her husband Sam seems oblivious, but maybe she'd prefer he remain in the dark. How can she admit the unthinkable--that she misses her freedom? In contrast, Hannah continues to endure round after round of unsuccessful IVF treatments. The process is taking its toll on her physically and emotionally--and, she worries, creating distance between her and her husband Nathan. She is godmother to Cate's son, but every time they get together, it's a trigger. Beautiful and unattached, Lissa is re-evaluating what it means to be an actress in her thirties. While she fiercely resists convention, she's also lonely. A chance encounter in the British Library with Nathan has her wondering if she missed her best chance at love when she introduced him to Hannah. As each woman longs for what the others seemingly possess, will their bonds of friendship sustain them in this liminal phase of their lives--or will their envy and desire tear them apart?
