It is 1834 and Daniel Shenkin a Welsh coal miner, political activist, and bare knuckle fighter has spent two years in the convict barracks prison of Sydney's penal colony. Together with his fellow convict Regan O'Hara they have been granted their 'Tickets of Leave' on the understanding that any misdemeanour would result in the removal of the Tickets and their full sentences imposed. Twenty years hard labour. They find themselves on the streets. Penniless but for the diamond pendant that Shenkin had hidden away in his ponytail head scarf. This together with the help of the woman he loves and Doctor Tarn from the convict ship The Runnymede, they go looking for the one time London fence Abe Goldspick to sell him the diamond. After a bare knuckle fight their sworn enemy Lord Feltsham, who wants both the woman and the diamond for himself, arranges a conspiracy headed by Feltsham's henchman Ketch. It results in Shenkin and O'Hara being sent to the notorious Port Arthur penal settlement. It is a brutal place from where few convicts ever return. But in a two-fisted action-packed story they plan an escape from what seems an inescapable prison. They do it in a way no one would dare risk. The hard way. It's a breathtaking adventure set in the grim world of the 19th century. Against all the odds Shenkin is a one-man fighting machine. Survival is his mantra he is not for the faint hearted. Take a deep breath and enter his harsh brutal world with great care.
