The Summer Without Men by Siri Hustvedt

From Library Journal: "A poet regains her balance following her husband's affair in Hustvedt's fifth novel (following The Sorrows of an American, 2008). After 30 years of marriage, Mia and Boris can easily finish each other's sentences, so closely are they enmeshed. But when Boris becomes enchanted by a younger colleague and tells Mia that he wants to take a "pause" from their marriage, shell-shocked Mia lands in a psychiatric hospital. Once released, she flees to rural Minnesota to spend the summer in the land of her childhood, where she hopes to heal while retracing the steps of her life. There, she comes to know a variety of females of all ages, each coping with the challenges of her particular stage of life. These interactions prove to be highly cathartic for Mia, and by summer's end she emerges stronger than ever before. While this tragicomic depiction of "women on the verge" sometimes veers off tangentially, in the end it proves to be insightful and thought-provoking. Readers may be reminded of the intelligent, evocative writing of Anita Shreve or Elizabeth Berg."
