Of course your mother says your book is perfect. She's your mother.
When you want a more objective evaluation, I offer professional copy editing and decades of experience. I'll find the grammar mistakes, structure problems, and gaps in narrative flow. Fact check, too.
At jcannonbooks you receive personal service at a reasonable rate. All books welcome, fiction and nonfiction, although I admit to being partial to mysteries. Newsletters and essays also accepted. The result is smooth and polished text, the kind that readers and publishers expect.
Mom will be even prouder.
