What Books Should be Made into Anime/Manga

So this is my 1st post on the sight *straps on helmet* I love books. There are a lot of good ones out there and are done so well that when there over I just want more. What are the top books you would want to be turned into an anime/mange (Mine are the Mistborn series...actually make that any book series by Brandon Sanderson ever)

After watching Another, I want other series that will keep me on edge like that show did. Any of Stephen King's novels. The book It was terrifying, and there are so many directions a person could go with that story line. Karen Marie Moning is another author. Her books on the dark fae would create great scripts.

Percy Jackson actually has a manga adaptation...at least for the 1st book. also the harry potter series would be awesome.

I actually like books the way as it is, since most of the movie adaptation didn't really give them justice. But it would be interesting to see an anime adaptation of The Secrets of the Immortal Nicholas Flamel.

Game of Thrones

Tales of the Otori series (Across the Nightingale Floor is the first book) Or the House of Night series
