May Sarton's love for Juliette Huxley, ignited that first moment she saw her in 1936, transcended sixty years of friendship, passion, silence, and reconciliation. In the extraordinary breadth and variation of these letters, we see Sarton in all her complexities and are privy to the nuances of her rich amitii amoureuse with Juliette, the preeminent muse and most enduring love of her life. The letters chart their meeting; May's affair with Juliette's husband, Julian (brother of Aldous Huxley), before the war; her intense involvement with Juliette after the war; and the ardent and life-enhancing friendship that endured between them until Juliette's death. While May's intimate relationship with Julian had not been a secret, her more powerful emotions for Juliette had. May's fiery passion was a seductive yet sometimes destructive force. Her feelings for and demands on Juliette were often overwhelming to them both. Indeed, Juliette refused all contact with May for nearly twenty-five years, the consequence of May's impulsive threat to tell Julian of their intimacy. The silence was devastating to May, but her love for Juliette never diminished. Their reconciliation after Julian's death was not so much a rekindling as it was a testament to the profound affinities between them. Although theirs had been a relationship rife with complications and misunderstandings, the deep love and compassion they shared for each other prevailed. Included in this volume are original drafts of and notes for an introduction May Sarton was hoping to complete.
