Courteous and understanding of my schedule and budgeting needs, Yvonne has been flexible when needed and always there when I got stuck. Not only have I received the best cover design experience, but I’ve gotten out of it a friend with amazing creativity, an eye for detail and putting pieces of a story together to create the perfect image that’s in my head, and someone who knows the craft inside and out. She has delivered cover packages, product design and animated book covers for my series with amazing accuracy for my vision, surprising me time and time again with the final result. Her covers for my books have been semi-finalists in cover contests and I’ve been recommending Ammonia Book Covers to every indie author I know!

I’ve used Ammonia Book Covers several times over the past couple of years, and she’s always exceeded my expectations. The quality, creativity, and professionalism of each cover has been superb. Just as important, she provides excellent customer service, and is willing to redo, revamp, and adjust as needed, in a very timely manner, to meet all my requirements as a self-published author. I enjoy working with her and plan to continue to do so for every book I complete.
