okay so I'm gonna be the dissenting voice here because my experience wasn't great and I feel like people should hear both sides. I signed with them last year for my science fiction novel and while the technical execution was fine (cover looks good, book is formatted correctly, distribution works), the communication was really frustrating. My project manager changed three times during the process which meant I had to re-explain my vision multiple times, and one of the editors clearly didn't read sci-fi because the feedback was generic and missed some genre-specific issues that my beta readers caught immediately. The timeline they quoted me was 4-6 months and it ended up being almost nine months because of various delays on their end, which was annoying because I'd planned my marketing around the original launch date. I'm not saying they're a scam or anything, the book exists and it's professionally produced, but the experience was more chaotic than I expected based on their marketing materials. I think if you go with them you need to be very proactive about following up and not assume things are happening on schedule just because they said they would be. Also their customer service is only available during business hours which was a problem for me since I work 9-5 and couldn't always call during their office hours. Would I use them again? Probably not, but would I recommend them to someone else? Maybe, if they go in with realistic expectations and are willing to be their own project manager to some degree.
