'Commitment is a majestic novel' Yiyun Li, author of The Book of Goose

A masterful and engrossing novel about a single mother's collapse and the fate of her family after she enters a California state hospital in the 1970s.

When Diane Aziz drives her oldest son, Walter, from LA to college, it will be her last parental act before falling into a deep depression. A single mother who believes that her children can attain all the things she hasn't, she's worked hard to secure their future. But when she enters hospital, her closest friend must keep the children safe and their mother's dreams for them alive.

At Berkeley College, Walter discovers a passion for architecture just as he realises his life as a student may end for lack of funds. Back home in LA, his sister Lina works in an ice-cream parlour while her wealthy classmates prepare for Ivy league schools, as she wages a high-stakes gamble to go there with them. And Donny, the little brother everybody loves, begins to drift towards a life on the beach, where he falls into an escalating relationship with drugs.

A resonant story about family, duty, and the attendant struggles that come when a parent falls ill, it honours the spirit of imperfect mothers, and the under-chronicled significance of friends. With Commitment, Mona Simpson has written her most important and unforgettable novel.

'Simpson is a national treasure. Commitment is a sweeping family epic that took me from one American coast to another, through a difficult but unforgettable time period, and through the growing pains of three remarkable siblings. I was immersed in their world and in Simpson's masterful vision for them. Simpson is so attuned to the family heart and oh dear Walter, Lina, and Donnie, have you forever moved mine'
