The book version of the movie Predestination starring Ethan Hawke.

This a very short book about time travel and the paradox that can happen while doing so.

I read it in a single sitting as it is just about 20 pages, but it is also one of my preferred Heinlein short stories.

La Isla y Las Cosas son las mejores historias del libro, las demás no son memorables así que la lectura de este libro puede ser una montaña rusa por su naturaleza de relatos cortos.

(Read the Spanish version).

This is a very weird book. I felt it was just two or three different books in one. The title does not even have anything to do with the whole story.

I later found out that the author himself forgot what he was writting about right in the middle of the book.
