A lot of these turned out to be YA, but I guess that's because I read a lot of YA in general, and it's such a popular genre. I'm sure there's more than what's on this list - but this is what I could think of right now.
Catching Fire and Mockingjay by Suzanne Collins

The Divergent Series by Veronica Roth
I know people who swear by this series - and one of these days, I may even get around to reading it. But currently, I'm not all that bothered either way. It could be cool though, maybe some day I'll give it a try.

I have to admit that I have no real desire to read this. I mean, never say never, but it doesn't really seem like my thing. That's not to say that other people won't enjoy it, but I really just have no drive to read this. Sometimes that happens. Everyone else is raving about something, and you're just there like... meh.
The Maze Runner Series by James Dashner
My best friend loves this - so eventually she will grind me down, and I will have to read it. Not that I mind, it's part of what friends are there for, after all. I tend to like dystopia, so I'll probably enjoy it.
Fangirl by Rainbow Rowell
Part of me is like, 'Ooh, that looks interesting!' and then part of me is like, 'But it's going to be some sort of contemporary romance, and those can get silly/annoying really fast.' So, yeah, in two minds about whether or not to read this one.
The Raven Cycle by Maggie Stiefvater
I've read Shiver - the first book in The Wolves of Mercy Falls series - by Maggie Stiefvater, and that was OK. The Raven Cycle actually looks quite interesting, and I wouldn't mind giving it a go.

Cloud Atlas by David Mitchell
I've heard good things about this but it's another one that has me in two minds. Part of me thinks it might be a little pretentious for my tastes - but then I think I'm being the one being snobby by making a snap judgement...
The Percy Jackson and the Olympians Series by Rick Riordan

Carrie by Stephen King
I will get around to this! It's on my tbr list! I will read it!
The Fifty Shades Trilogy by E L James
I am in no way a prude (I read fanfiction for Chrissakes!) but I really couldn't care less about Fifty Shades of Grey. All power to you if you like these books - you have the right to read and like to read whatever you want - but I just don't give a damn to be honest. This won't be on my tbr list for the foreseeable future.
