The Alignment of Stars

Anyone remember John Carpenter's "In the Mouth of Madness"? There was a puzzle to locating the missing writer in the covers of his books. There was all these red lined shapes that seemingly had nothing to do with the cover art. Once the shapes were cut out of the dozen or so book covers they could be put together as a map of New Hamshire and led to a mysterious town there. Imagine a fanous frontier author hiding a puzzle in the covers of his novels where the cover art has a planet in the background. Once the planets are identified the form a sort of map by drawing lines beteween their star system and the intersection of those lines is the secret location.
