Dear Miss Snark;
I have written my fabulous memoir about my journey through sex, drugs, rock and roll and Cancer. I am still in the process of “polishing” the practically completed manuscript.
The research I’ve done has not provided a clear answer to this question: When is the proper time to start sending queries to agents for a memoir? It this like a novel in that it should be absolutely complete with all spelling and grammar checked and rechecked? Or because it is non-fiction, can it be submitted as a proposal and partially finished?
Of course, my query letter will be brilliant based on all of the things I’ve learned from you, but I want to make sure to have everything else ready when my dream agent contacts me.
Memoir needs to be finished before you query. And more than spelling and grammar, you'll need to let it sit untouched and unread for at least a month, and then look at it one more time before you start querying.
You get one shot on this. Don't fuck it up by querying before your ms is ready.
