A key point about writing genre novels (and what ISN’T a genre these days) is to read heavily in the genre you wish to write in.
Which, yes, okay… that’s true. If you want to write Romance, read Romance. Take a look at modern trends, look at how the market is going, then take your story and aim for the biggest readership you can get. That’s all fine.
Here’s the problem: ONLY reading within your genre.
