A lot of adults, myself included, read YA. I love that. The YA market is full of great books. There's no reason why adults shouldn't enjoy the books.
Having said that, I think when adults read YA, they have to read as if they are teens. Here's what I mean. When I write, I write for teens. They are my target audience, not the adults reading YA. It's funny because when I read reviews of YA books, I notice a difference between what adults think about the books and what teens think about them.
When I read a YA book, I tap into my inner teenager. That's not tough for me because she never left. She's my emotional side. The part of me that lives for perfect moments. In short, she's way more fun than grown-up me. And she's the one who loves YA books. They're meant for her. Maybe part of the reason why I enjoy reading and writing YA is because I can relive that time of my life. I can forget adult responsibilities for a little while and be a teenager again. That's a great thing. But I also take that into account when I review books. I know I'm reviewing a book meant for teenagers, not adults. So I let my inner teen out and share her thoughts in my review. It allows me to love a naive character and accept that an MC is making a choice based on her heart and not what she should do.
Do you think there's a difference between teens reading YA and adults reading YA?
