The beloved author of bestsellers Women Talking, All My Puny Sorrows, and A Complicated Kindness returns with a funny, smart, headlong rush of a novel full of wit, flawless writing, and a tribute to perseverance and love in an unusual family.

Fight Night is told in the unforgettable voice of Swiv, a nine-year-old living in Toronto with her pregnant mother, who is raising Swiv while caring for her own elderly, frail, yet extraordinarily lively mother. When Swiv is expelled from school, Grandma takes on the role of teacher and gives her the task of writing to Swiv's absent father about life in the household during the last trimester of the pregnancy. In turn, Swiv gives Grandma an assignment: to write a letter to "Gord," her unborn grandchild (and Swiv's soon-to-be brother or sister). "You’re a small thing," Grandma writes to Gord, "and you must learn to fight."

As Swiv records her thoughts and observations, Fight Night unspools the pain, love, laughter, and above all, will to live a good life across three generations of women in a close-knit family. But it is Swiv’s exasperating, wise and irrepressible Grandma who is at the heart of this novel: someone who knows intimately what it costs to survive in this world, yet has found a way—painfully, joyously, ferociously—to love and fight to the end, on her own terms.
