In a fascinating dual biography of these two American expatriates, Brenda Wineapple tells the story of a powerful, poignant relationship rooted in love, longing, and smoldering rivalry, a relationship so profound that when it ruptured in 1914, sister and brother never spoke to each other again.

Wineapple reconstructs those exciting turn-of-the-century years when Gertrude and Leo fell in love with the people and ideas that later helped drive them apart. In this, the first biography to be written about Leo Stein - and the first completely researched book about Gertrude to appear in more than twenty years - Wineapple unearths a wealth of new and rare material, including an early Gertrude Stein manuscript, printed here for the first time.
