I have written a book that is intended to make readers laugh occasionally. That is a deadening description, I know, but one can hardly call one’s own book “witty,” and “humorous” sounds like it belongs in the Humor section of the bookstore, which my novel does not. (It’s Upmarket fiction.)
The best I can come up with for a query is “light-hearted,” but I would love to have your perspective on this, as I think that humor can be a big selling point. Or do I simply let the pages speak for themselves?
You're right to avoid calling your book witty or humorous.
That's like Felix Buttonweezer calling himself handsome and erudite on Match.com (Betty finally had enough of Felix rewashing the dishes after her, and has run off with a chainsaw sculptor) when his photo is right there, and he lists his favorite book as "Cents and Sensibility by Jane Austin".
Humor IS a big selling point for me.
I think if you look at almost every novel I've sold there's a strong element of humor or wit.
Even in old sobersides Jeff Somers.
So, how do you show rather than tell?
The answer is right here.
