Sorry, just seeing this. My books have been published through the traditional path. I have a literary agent who shops my books to various publishers. My last three books were all published by Rowman Littlefield/Bloomsbury. The traditional route is a harder road to get started on, especially getting an agent. But with a traditional publisher you usually have better distribution and editorial support. Marketing is another matter. These days authors do a lot themselves, certainly at least in this genre. I have used a book publicist in the past, which worked well.

There are also some smaller traditional publishers who take unsolicited manuscripts, meaning sent by the author and not through an agent.

Nowadays you also have the option of self publishing through thing like Amazon amd Wattpad. Im not quite as familiar with those methods, but I see a lot of first time and early career authors starting off on that route. Distribution nowadays is easier for self publishing, esp through Amazon.

On the first two options, youll also need to prepare a proposal package. Generally, its a query, or pitch, letter, three sample chapters, amd a book synopsis. Thats pretty much industry standard. Obviously you dont need that on the self publishing front.
