Half-brothers Byron and Clancy Wilson are inseparable during their childhood. They run wild in the dark valleys of the Blue Mountains, run riot during their school years in Katoomba, and run afoul of the ogre of the town, Constable Barnaby Clout. But it is a love triangle between the brothers and emerald-eyed Violet Kefford, as well as a dramatic jewel heist, that ultimately tests their unconventional family. The Forgotten World is a breathtaking story that lyrically charts the landscape and people of the Blue Mountains in the late 1800s, and sees real characters in Australian history, such as Sir Henry Parkes, artist Julian Ashton and Lord and Lady Carrington dancing through its pages. Poignant and unforgettable, it plumbs the depths of family loyalty and betrayal.
