Interesting novel. But the last 10% are blurred. However, in the last pseudo-chapter the author himself admits that he has exhausted his inspiration. So the ending is rather quick and meaningless.
A relatively good novella. It's just a pity that it was abandoned. Besides, one small remark: the main character is not restrained! He's just weak at first. And then, when he gains enough strength, he behaves completely unrestrained.
