Some series I've been meaning to start:
1. Twilight by Stephenie Meyer
Yup. I never read Twilight nor I ever felt like I wanted to but it's a new year and I deserve to know what actually happens in the books because I honestly saw the first three movies then quit.
2. Delirium by Lauren Oliver
3. The Bodies We Wear by Jeyn Roberts
4. Miss Peregrine's Home for Peculiar Children by Ransom Riggs
5. Unwind by Neal Shusterman
Again this is all off the top of my head. Let me know what series you want to start this year in the comments, Goodreads, Tumblr, Instagram, or Twitter ;)
