In March 1941, Virginia Woolf filled her pockets with stones and drowned herself in England's River Ouse. Her body was found three weeks later. What seemed like a tragic ending at the time was, in fact, just the beginning of a mystery.

Six decades after Virginia Woolf's death, landscape designer Jo Bellamy has come to Sissinghurst Castle for two reasons: to study the celebrated White Garden created by Woolfs lover Vita Sackville-West and to recover from the terrible wound of her grandfathers unexplained suicide. In the shadow of one of England's most famous castles, Jo makes a shocking find: Woolfs last diary, its first entry dated the day after she allegedly killed herself. If authenticated, Jo's discovery could shatter everything historians believe about Woolf's final hours.

But when the Woolf diary is suddenly stolen, Jo's quest to uncover the truth will lead her on a perilous journey into the tumultuous inner life of a literary icon whose connection to the White Garden ultimately proved devastating.
