Frontline Publishing or Another Option? Need Best Suggestion!

Hi fellow writers,I’ve been researching publishing services for my upcoming book, and Frontline Publishing keeps showing up as a full-service option. They seem to offer everything from ghostwriting and book publishing to marketing. However, I don’t want to rush into anything without getting some honest opinions. Has anyone here used Frontline Publishing before? How was your overall experience? Also, are there any better alternatives you’d recommend based on personal experience? I want a service that communicates well, delivers on deadlines, and helps make the book a real success—especially with marketing and distribution. Your suggestions and feedback would mean a lot. I’m hoping to make the best possible choice with my publishing partner. Thanks in advance for sharing your thoughts!
