From the book cover:
Their childhood and adolescence were overshadowed by the Great War. Now, in its lonely aftermath, Rose and Mary Aubrey find themselves deprived of the guiding strength of their cousin Rosamund when she marries a man of dubious morals and intolerable vulgarity. Retreating to an inn on the Thames, they find a haven of security with old friends.
Into this fragile Eden a new, disruptive force is introduced: Rose discovers the power of love, and, confronting her own sexuality, learns to delight in it. With extraordinary fierceness and candor, Rebecca West has written a portrait of sexual awakening, one that allows her characters an uncanny glimpse of our own age.
