If you know someone who is publishing a book the self publishing route, here's a tip: make sure they know the printers guidelines before they create the files for the book cover and the manuscript. In my case that means knowing in advance what they use for .dpi image size, CMYK vs. RGB color, and text "blackness." I've spent hours and hours ( the key word is trying) to get things right for the Secret Speakers cover in order to meet guidelines for the book printer. Offset printing is definitely a different animal than digital printing. Long, long days working until I can't see straight. Lots of Pepsi. This is the final product.
I've come to the conclusion that independent publishing is like running a marathon with dozens of finish lines. You think you're done, then WOOPS, you realize there's something else. Someplace warm with no computer and no cell phone sound really good right now.
