A largely legal drama about the case of Bruce Trevorrow, an aboriginal man. He was born in 1955 and lived with his family at "one mile camp" near the Coorong in South Australia (a lake, estuary near the mouth of the Murray River, a bit like the Mississippi in the US). They lived in a shack, described in the book as being made from 44 gallon drums hammered flat and nailed to a wooden frame. Nice and warm in summer, pretty cold in winter.
When he was 2 years old he had a fever and his father carried him to the nearest town and got someone to drive him to Adelaide. The father could not go with them as he had other children waiting at home. Bruce went to the Adelaide Children's Hospital. However his parents could get no information about his condition or even his whereabouts. Eventually a letter was sent to them (called "the lying letter" by one of the lawyers, Joanna Richardson, in the long running case), completely fobbing them off. Bruce's parents (possibly illiterate, not sure about this) were no match for the state authorities.
Bruce had in fact been adopted by a white family and did not have contact with his birth family for many years. He lived a troubled and unhappy life, marred by alcohol and violence and the accompanying ill health that many at the bottom of the social ladder suffer from.
Australia had a policy for many years (explicit and covert, with a different expression in different agencies) of removing Aboriginal children from their families. In many cases it stemmed from a policy aimed at ensuring that the children did not grow up to be "aboriginal" in culture. It was described as "genocide" in one major government report (something the authors regretted as all the ensuing debate was about the term rather than the impact of the policy).
The book has a wider relevance than Australia. It explores the way the marginalized are treated by the state powers including those services that are meant to be there for their protection. I won't give away how it ends.
