Nobody seems to think this is a good idea. Who would want to read a book about a house with bats in it? It'll terrify the youth and gross out their parents. It's like a book about rats in your sweatshirt.
Except it's not! Bats are rather incredible and while they don't technically belong in houses, I do think we can discuss it occasionally because it can be unavoidable at times. Bats are determined little dudes and you'd be amazed where they can fit. Okay, I admit it. I do currently have bats in my house.
