/lit/ - Literature

I'm trying to write a book that will appeal to the largest US demographic possible.

First: it will be a Kindle ebook, so it needs to be tailored to the Kindle's userbase.

Looks like Southerners and Midwesterners are not my main target market.

So first, I need something that appeals to the middle of the road female Starbucksy twentysomething college graduate from California or the East Coast north of DC.

It needs to be genre fiction, because that is what sells. Female protagonist. Romance sells very well, and younger women are open to it due to Twilight and Fifty Shades of Grey.

I think some kind of paranormal book in a contemporary setting, because contemporary settings require very little imagination to understand or care about. Hence the popularity of Zombie Apocalypse stuff, which is essentially "the floor is lava" for adults.

I'm on the fence about how central the romance should be. Should it be romance that develops as a result of fighting monsters together, or between the human woman and the semi-monstrous Mr Handsome? I'm not sure if I want to alienate male readers entirely by having the protag fall in love with a serial killer with high cheekbones, but on the other hand, men are scrubs who don't buy many ebooks.

What do you think, /lit/?
