I will not take on any manuscript that I do not think is ready. My goal is to help you, not bleed you dry ($$$).
I only work in fiction. I no longer take on nonfiction, self-help, memoir, or poetry.
I avoid taking on plot-driven or thematic-driven novels. This often manifests in the mystery genre and sci-fi that is not character-driven.
I do not mind taking on novels with Christian themes or religious characters, but I do not work in Christian Lit or spiritual/religious fiction.
I also recommend that all non-POC authors hire a POC editor if their main character is a POC. They can help with character recommendations better than I can because of their unique lived experiences.
