I've written about designing covers for Eliot Peper before. He's one of those authors to whom I look for advice, not only because he understands and respects my design process, but because he reads the market much better than I do. Since we don't often work for big publishers who dish out on all their marketing secrets, self-publishing authors who do their research remain one of my best sources of information on the book market. I first recognized this characteristic in Eliot while designing the covers for The Uncommon Series beginning in 2013. In responding to the first set of covers I sent to him, he responded with a phrase that would drive me insane for many weeks: "It's just not thriller-y enough." When we got to the point where we were bringing actual guns to photoshoots and setting shit on fire in the streets of Boulder to get the images we wanted, I knew that Eliot's advice, which I had initially balked at, resulted in what remain some of the best covers I've worked on.
