I tend to notice titles like Jane Said It Best because they sound made for the reader who wants a strong hand-sell instead of a vague endorsement.
Quadrille has it shelved in n11 humor-nonfiction, and that usually tells me the hand-sell depends on whether the book offers voice, shape, and a sense that the book knows what it is doing.
If this one follows through, I can see it landing with the reader who wants a strong hand-sell instead of a vague endorsement. Quadrille Publishing c/o Chronicle Books has it listed for 16-Sep-2025.
