Isso soa como Se em um Viajante Noturno de Inverno por Ítalo Calvino.
Eu não tinha certeza se era qualificado como SF & F, mas é mencionado no isfdb .
Aqui está a sinopse da wikipedia ("viajante" nos EUA)
If on a winter's night a traveler (Italian: Se una notte d'inverno un viaggiatore) is a 1979 novel by the Italian postmodernist writer Italo Calvino. The narrative, in the form of a frame story, is about the reader trying to read a book called If on a winter's night a traveler. Each chapter is divided into two sections. The first section of each chapter is in second person, and describes the process the reader goes through to attempt to read the next chapter of the book he is reading. The second half is the first part of a new book that the reader ("you") finds. The second half is always about something different from the previous ones and the ending is never explained. The book was published in an English translation by William Weaver in 1981.
Os livros começam com o que parece ser Se em uma noite de inverno um viajante , mas o capítulo 2 continua na segunda pessoa.
...Wait a minute! Look at the page number. Damn! From page 32 you've gone back to page 17! What you thought was a stylistic subtlety on the author's part is simply a printer's mistake: they have inserted the same pages twice.
Você troca o livro por outra cópia.
Then from the very first page you realize that the novel you are holding has nothing to do with the one you were reading yesterday.
