Sometimes authors do this for you. For example in The Sirens of Titan by Kurt Vonnegut he quickly introduces a time travelling character who tells the main character vaguely what will happen to him throughout the book, leaving him with a picture of beautiful Sirens on Titan, Jupiter's largest moon. From then on you wonder how the main character will end up living on Titan. Vonnegut even centers the title of the book around this kind of suspenseful trick. When done by a skillful author, this kind of pre-reveal can be really engaging.
