Answer: We have a number of US maps that would help with your project. My recommendation is that if you are publishing a book you probably want to work in Adobe Illustrator so that you can produce the best and sharpest graphic.
From Illustrator you can customized all you want and then export it as an .eps or .ai file for your desk top publishing program where you can lay out the book.
I have attached a black and white jpg file of one of the maps with capitals so you can see what it looks like. We also have this in color. All of our illustrator maps are completely editable, each state or block of text is an individual element. You might also want to use some of our individual states to give more detail when you are describing that place.
Hope this helps, please contact me if you need further info
