Patrick Rothfuss (international bestselling author and hirsute iconoclast) will read your manuscript and give you critical feedback.

On the upside: I'm willing to read your whole book, as it's easier for me to get a feel for the story that way. Let's call it up to 175,000 words.
The downside: It might take me a while to get to it. We’ll schedule this based on when your manuscript will be ready and the endless madness of my own schedular constraints.

My feedback will consist partly of me printing out and reading through your manuscript, scrawling notes and dirty words in the margins.
I won’t write you up a detailed critique because that’s not how I roll. But after I'm done, we'll chat for a bit. Phone if you want. Or Zoom or skype. Whatever you're most comfortable with. We'll discuss my thoughts about the book, what seems to be working well, what might need more work. We'll talk about writing craft, and I’ll offer any suggestions I might have. Then I’ll mail you back the manuscript with my notes on it.
