Amazon book recommendation filter?

I'm a teenage girl with Kindle PC on my laptop, and I'm wondering if Amazon has any way to filter the genre of books it recommends to me. I keep getting recommendations for adult fiction novels vs. young adult fiction/fantasy novels, which I'm more interested in. I think one time I accidentally downloaded a free adult fiction book, but I deleted it once I read the first page. I didn't realize what it was from the summary.
