Oh my…. Comic is your expertise 😁. What an interesting book it’s going to be.
Publishing a book sounds like a wonderful dream.
If it's self-publishing, it might require more money spent and sales might be hard to get. If you are publishing through an agent, it might not cost much depending on the negotiation, and sales might start coming in as soon as published.
Either way, If you think that now is the best time, do it; putting it beside might make you not do something about it.
One step at a time and before you know it, a distance dream will become a reality.
I wish you best of luck, Jeff 😊
