Well there was an ending, and it fit with the style of the novel. If you don't like self appointed white knights, this isn't the book for you. If you like men congratulating themselves for a story where all men are bad, all women are victims and they learned this by visiting a women's prison for an afternoon, then go for it. If you don't mind that you won't care they wrote paper thin female characters who are either male characters relabeled or independently moody without explanation.
It was a nice setup. Oh, but also completely glossed over a hostage plot point between two writers and an editor which completely dismisses one part of the setup. Pretty amateurish really, which was the biggest surprise to the book.
