This zero (additional) volume of the epistolary novel is for those who for some reason were prevented from reading the three main ones. It’s expensive, or the principles don’t allow you to pay for information objects, or you don’t want to bother with Internet payments, or you don’t have time for three volumes of who knows what, or something else. After all, two thousand paragraphs takes three times less time than six. But not such global reasons as dislike for science fiction in general, or for the works of a given author in particular. Here you can get acquainted with the novel in a short version for free.
