Anna, a self-sufficient and reliable single mother, packs her bags one day for a short vacation to Italy. She leaves her beloved daughter at home in London with good friends. When Anna doesn't return, everyone begins to make excuses, until the likelihood that she might not come back at all becomes chillingly clear. In this dazzling work of suspense, Sarah Dunant interweaves parallel narratives that are stretched taut with tension even as they raise difficult questions about love, trust, and accountability. We are challenged, unnerved, and ultimately exhilarated as Dunant redefines the boundaries of the psychological thriller.
