Are Book Publishing Services Worth the Investment?

[Cecilia]

I’ve been exploring options for getting my manuscript out into the world, and I keep seeing various book publishing services advertised. How do you know which ones actually deliver quality results? Are these services more beneficial for first-time authors or can experienced writers benefit too? How do they compare with self-publishing independently? I’m curious about real experiences—has anyone used these services and found them worth the cost and effort?
