While some agents ask for a specific number of pages or chapters in their submission guidelines, others request them because they found your pitch promising. Either way, your first few chapters need to draw the agent or editor in enough to want to read the rest of your manuscript.
The Hundred-Page Critique is an evaluation of the manuscript's opening and outlines the strengths and weaknesses in regards to plot, characterization, voice, world building, pacing, etc. The critique will be returned to you in form of an editorial letter and also includes in-document comments, deletions, and insertions.
This service includes a Query Letter Critique (one pass).
Rates: $275 (single pass); $400 (incl. a second pass); optional line edits = $75 per pass; optional synopsis critique = $20
Your manuscript should be formatted as follows: double-spaced, one-inch margins on all sides, half-inch indent for a new paragraph, numbered pages, page break after the end of a chapter, 12pt Times New Roman. Please note that I can only offer this service for your first hundred pages.
