When all that you know comes crashing down, do you run? Or face the truth? Ruby Cardel has the semblance of a normal life, a loving boyfriend, a fulfilling career, but in one terrible moment, her life unravels. The discovery that the death of her sister, Jamie, was not an accident makes her question all she has known about herself and her past. Travelling back home to Lyrebird Hill, Ruby begins to remember the year that has been forever blocked in her memory. Snatches of her childhood with beautiful Jamie, and Ruby's only friendship with the boy from the next property, a troubled foster kid. Then Ruby uncovers a cache of ancient letters from a long-lost relative, Brenna Magavin, written from her cell in a Tasmanian gaol where she is imprisoned for murder. As she reads, Ruby discovers that her family line is littered with tragedy and violence. Slowly, the gaps in Ruby's memory come to her. And as she pieces together the shards of truth, what she finally discovers will shock her to the core, about what happened to Jamie that fateful day and how she died.
