A captivating story of family secrets, a sister's betrayal and a father's crime.

Miss Isobel Clara Macleod, youngest of the seven children of Major Sir Angus Hutton Macleod, Surveyor-General of the colony of New South Wales, had the singular misfortune to know that at seven o'clock that morning her father was going to die.

September, 1851. Sydney, city of secrets and gossip. Seventeen-year-old Isobel Macleod is determined to save her father because she loves him. But when she dares to trespass in a forbidden male world, she will be plunged into social disgrace. A wave of ill fortune threatens to swallow up her family and their stately home, Rosemount Hall, 'the finest house in the colony' on the foreshores of Sydney Harbour.

Is Isobel to blame for her family's fate or does the cause lie further in the past? When Isobel was four, Major Macleod returned from an expedition with two 'souvenirs': an Aboriginal girl who became her friend and two opals fashioned into a dragonfly brooch for her mother.

When Isobel inherits this 'unlucky' heirloom, she wonders if the terrible dreams it summons are a curse or a gift. Now Isobel's hopes for her future depend on a charming bohemian who encourages her hidden passion to become an artist. Will she now be permanently exiled from her family home? Or will she be transformed into a new self, like a magnificent dragonfly emerging into the sunlight?

Inspired by Elizabeth Bay House and the other grand villas of Sydney's Woolloomooloo Hill, The Opal Dragonfly tells the bittersweet story of an ambitious family's fall from grace and a brave young woman's struggle to find her true self.
