Yip-Williams toggles between optimism and despair, between believing she’ll defy the statistics as she had so many times in her life — “odds are not prophecy” — and trying to persuade her husband to confront their harrowing reality. She makes bargains with God, just as she did as a young girl when, in exchange for her poor vision, she asked for a soul mate one day. (“God accepted my deal!”) She posts pictures of contented normalcy on Facebook — of meals cooked, a car purchased — but rages at her husband, healthy people, the universe and, silently, at the moms at a birthday party who ask how she’s doing. “Oh, fine. Just hanging in there,” she replies, while wanting to scream: “I didn’t deserve this! My children didn’t deserve this!” She frets about the “Slutty Second Wife” her husband will one day marry and the pain her daughters will experience in her absence. And, near the end, she oscillates between being game to try every possible treatment and accepting that nothing will keep her alive.

“Paradoxes abound in life,” Yip-Williams writes in a heart-rending letter to her daughters; she asks us to confront these paradoxes with her head-on. One of the paradoxes of this book is that Yip-Williams writes with such vibrancy and electricity even as she is dying. She moves seamlessly from an incisive description of her mother as “the type of woman who sucks blame and guilt into herself through a giant straw,” to the gallows humor of “Nothing says ‘commitment to living’ quite like taking out a mortgage,” to the keen observation “Health is wasted on the healthy, and life is wasted on the living.” Unlike the woman in her support group who, after being given a terminal prognosis, defiantly declares, “Dying is not an option,” Yip-Williams prepares meticulously for her death while paying close attention to the life she will one day miss: “the simple ritual of loading and unloading the dishwasher. … making Costco runs. … watching TV with Josh. … taking my kids to school.”

This memoir is so many things — a triumphant tale of a blind immigrant, a remarkable philosophical treatise and a call to arms to pay attention to the limited time we have on this earth. But at its core, it’s an exquisitely moving portrait of the daily stuff of life: family secrets and family ties, marriage and its limitlessness and limitations, wild and unbounded parental love and, ultimately, the graceful recognition of what we can’t — and can — control.

“We control the effort we have put into living,” Yip-Williams writes, and the effort she has put into it is palpable. Of all the reasons we’re drawn to these memoirs, perhaps we read them most for this: They remind us to put in our own effort. It would be nearly impossible to read this book and not take her exhortation seriously.
