I read a couple of the Twilight books in my early twenties and found them well written and a fun escape. They're a great read for young adults because it let's you escape the realities of life. It's a fun easy read.
I feel like when we are young we're faced with new responsibilities that can be difficult to handle We're learning so much and life can be overwhelming at times. Twilight gives you romance, fantasy and a strong lead character who isn't your typical protagonist. You get to explore a world that is very different from the one we live in. Check it out!
