What, you've never heard of John Boyle O'Reilly before? Yeah, I hadn't either. (Well, actually I had, since the U2 song "Van Diemen's Land" is about him, but I didn't remember that when I started reading this book.) Anyway, he's an interesting guy, having escaped from prison in Australia and lived the remainder of his life in the United States as a prominent journalist and civil rights activist.
He was also a novelist, in the sense that he wrote this novel. While the plot is inventive and the characters are cool, the structure does not bear the mark of a practiced writer of fiction. The plot leads one to expect an epic climax but then peters out as the end approaches. Nevertheless, this is a good novel in the sense that Uncle Tom's Cabin is a good novel. It's entertaining, for the most part, and makes valid, serious points in advocating for reform of the penal system and for human liberty and dignity in general. It's also got several great scenes and interesting settings. It's worth your time both as a historical artifact and a work of entertainment.
