In a small country town during one long, hot summer, the Bloom family begins to unravel. Marital secrets, new and long-hidden, surface - with devastating effect.

Martha is straining against the confines of her life, lost in regret for what might have been, when an old flame shows up. In turn, her husband, Mike, becomes frustrated with his increasingly distant wife. While teenagers Tilly and Ben are about to step out into the world, nine-year-old Ada is holding onto a childhood that will soon be lost to her. When Ada discovers an abandoned well beneath a rusting windmill, she is drawn to its darkness and danger. And when she witnesses a shocking and confusing event, the well's foreboding looms large in her mind - a driving force as events lead inexorably towards tragedy.

The Last Summer of Ada Bloom is a beguiling story about the fragility of family relationships, about the secrets we keep and the power they hold to shape our lives. And about the love that somehow holds it all together.
