Iseult Gonne was the daughter of Maud Gonne and the French politician and journalist Lucien Millevoye. She attracted many admirers -- among them distinguished authors such as W. B. Yeats, Ezra Pound, Arthur Symons, Lennox Robinson, Francis Stuart and Liam O'Flaherty. Yeats proposed marriage to her, Ezra Pound had a secret, passionate love affair with her and she married Francis Stuart. This book contains her hitherto unpublished letters to Yeats and Pound, edited and annotated by Anna MacBride White (Maud Gonne's granddaughter), Christina Bridgwater (Iseult's granddaughter) and A. Norman Jeffares, the distinguished Yeats scholar. It also features photographs, paintings and drawings of Iseult, some of which have not been published before.
