What is the best way to learn how to speed read?

Hello everyone, I was just wondering if there were any good methods on how to read books/texts at a faster pace. I'm 16 and I really wanna get back into reading good books, but I don't always want to read the good books that are large because it takes me forever to finish them. I just wanna know if there are any good tips on how to start out fresh and how to use these tips effectively. Thank you all who answer :) And when I mean big books, I mean like Twilight (I am not a fanatic), The Overachievers, Harry Potter (also not a fanatic) lol, ya know, like, 400-600 page books.
