The Hallo-Wiener by Dav Pilkey

4.0

This book has a little problem, namely: Hallo, Wiener!: An Erotic Gender Swap
which is the next thing that comes up when you search this one up on Goodreads.

"Her wish-come-true is no trick…and all treat!
Katrina has an awkward girl-crush on her BFF. A doomed girl-crush, since Sophie is as straight as hell.
But through some Halloween magic, Katrina wakes the next day as a man. And not just any man—the sexiest one she’s ever seen. Who happens to be just Sophie’s type .
Though she’s freaked out, Katrina realizes that being in a man’s body…is her only chance to get into Sophie’s body.
One click to see how one SWITCH can really turn these girls on!"

I mean, not the absolute worst thing to pop up when you've got a wholesome story about a weiner dog whose resemblance to a hot dog turns out to be his greatest strength. But not exactly what I'm guessing most people are searching.

I guess this could be an attempt at guerrilla marketing. You name your erotic fiction "Green Eggs And Ham-Sized Penises" or something, and then maybe some people click out of curiosity?

I've seen worse marketing. I've done worse marketing.
