Spleen
Dalkey Archive Press first introduced readers to this best-kept secret of British literature with the hardback Collected Writings of Olive Moore in 1992. Spleen , the best of the author`s three novels, tells the disturbing story of a woman who goes into self-imposed exile to an island off the coast of Italy after giving birth to a deformed child. Filled with self-reproach and guilt about her son and her life (having yearned to give birth to something new and rare, she blames herself for her son`s deformity), Ruth broods on what it means to be a woman ( nature`s oven for nature`s bun ) and the inequalities between the sexes. Filled with the colors and beauty of the Italian countryside and in a style similar to Virginia Woolf`s, Spleen challenges the assumption that women can`t help but be tender and maternal, that their heads are ever-enlarging hearts.
