There will only ever be one “first submission for my novel” to a literary agent (full manuscript or otherwise). Last week, I achieved that milestone.
At the conclusion of my Pitchapalooza win a few weeks back, an agent contacted me and wanted to see some material for my (as-yet-unfinished) book. She gave me a list of items to prepare as a book proposal to showcase the story and my writing ability before the full manuscript is completed. She gave me three weeks.
