Wait like you just want to know my personal favorite kind of novels? Or what kind of stories do well on tapas?
I think my favorites are drama/gothic fiction type stories. I like Dickens novels, but I'm also a fan of fantasy series like Atherton, (hope i'm spelling that right, it's been years since i read that series) and mystery series as well. If I can get a series with action and comedy like "The Brixton Brother's Detective Agency" and "Almost Super" that's a win-win.
That said, for what does well? Probably all kinds of romance are the most popular genres. I've gained a fair amount of traction for my first romance novel on here.
