I have used them in the past for publishing projects of mine, one was a children's book series and another a book about women who worked as spies during WWII, both were very enjoyable to edit and publish. They are professional and knowledgeable. There isn't anything I dislike about their service. It is important that you understand what you're getting into before you hire anyone. Do your homework and make sure they can deliver quality work at an affordable cost. Publishing books and working with editors.
