Isa & May - Margaret Forster

Isamay's unusual name comes from her two very different grandmothers, Isa and May, who were both present at her birth and who have both formed and influenced her whole life in very particular ways. Now almost thirty, Isamay is trying to write a thesis about grandmothers in history but is instead constantly ambushed by the startling secrets her own family has been keeping. When disturbing truths are revealed that force Isamay to examine her own certainties, will her grandmothers be able to build a bridge across the generations?
