I thought I was ready for prime time. I had even begun sending queries to potential literary agents in an effort to publish my novel. When Tessa read the samples I'd been sending, she was supportive, but suggested I hold that process up and go through a developmental edit. The result is so much better! She gave me detailed insights, helped me breathe more dimension and life into my characters, and avoid some of the classic storytelling missteps that can degrade readers' experience. I feel great about where my book is now - thanks so much Tessa!!

Author & Business Coach

Before I met Tessa, I had never dreamed of writing a book. I was completely intimidated by the process, even though I had been a writer. Her enthusiasm and encouragement got me through my resistance and fear of failure. She helped me map out a plan and the periodic check-ins have been enormously helpful at keeping me on track through the first draft and subsequent revisions. Whenever I hit a wall, she was always available to help me organize my thoughts to keep the words flowing. Now, it doesn’t feel like an impossible feat and I am excited about publishing my book as well as pursuing other writing projects with her guidance.

Developmental Editing

Take your draft to the next level

This high-level critique is the best place to start if you’ve finished your first or second draft and aren’t quite sure how to begin the revision process. I’ll read your full manuscript and provide a detailed editorial letter offering feedback on your book’s elements, such as structure, voice, pacing, setting, and more, as well as a detailed list of suggestions for how to tackle your revision process to make the next round of edits smooth sailing.

This is the edit for you if your next step includes discovering your flow and focusing on the structure of your chapters, or if you’re looking for some big-picture feedback on what’s working and what’s not. Typical edit letter length is 5–7 pages.

Please note that this does not include line edits. $0.008/word


Full Manuscript Critique

Get your book ready for agents and publishers.

This is ideal if you’ve gone through a round or two of big-picture edits and are looking for thorough feedback to take your book to the next level before sending off to beta readers or agents. This detailed critique includes an edit letter (the Developmental Edit) plus line edits that will leave you with detailed margin comments throughout the document to point out strengths, weaknesses, and suggestions to push you further. A strong focus will be on providing solutions to “showing vs. telling,” character development, use of dialogue, awkward sentences, sensory descriptions, narrative voice, pacing problems, structure, plot holes, and how to best bring the story forward so that your audience won’t be able to put your book down.

This edit is all about my giving you everything I can to help your book shine! This edit also includes a 1-hour follow-up phone call to brainstorm any areas still in need of help, or to give further advice on your next steps.

A complimentary critique of the first 5 pages is available before you commit. $0.018/word
