In the early 1800s the penal colony of Botany Bay was an unforgiving and harsh place. Isabella O'Shea is transported to New South Wales for wounding a member of the British aristocracy who raped her, so it is understandable that she loathes members of the upper class and the system that punished her; sentenced her to seven years transportation. Tiger Carstairs is rich, ambitious and English-so is it any wonder she is determined to hate her new master. Tiger dreams of making a new life beyond the aptly named Blue Mountains, so called because of the perpetual haze of blue surrounding them. Mystic Mountains is a story of courage and persistence-traits that were essential for the settlers who carved out a new life in a raw land where suffering and heartbreak were commonplace. Isabella and Tiger face tragedy and many hardships in their quest for a new life in this untamed land.
