His Illegal Self by Peter Carey

His Illegal Self is the story of Che — raised in isolated privilege by his New York grandmother, he is the precocious son of radical student activists at Harvard in the late sixties. Yearning for his famous outlaw parents, denied all access to television and the news, he takes hope from his long-haired teenage neighbor, who predicts, They will come for you, man. They'll break you out of here.
 
Soon Che too is an outlaw: fleeing down subways, abandoning seedy motels at night, he is pitched into a journey that leads him to a hippie commune in the jungle of tropical Queensland. Here he slowly, bravely confronts his life, learning that nothing is what it seems. Who is his real mother? Was that his real father? If all he suspects is true, what should he do? 


This book has it all. It's original, compelling, has wonderful descriptive writing, a unique plot, and characters that are distinctive and memorable... but it is still missing something.
Perhaps why. Why did Anna do what she did? It never really made sense to me.
