The Hunger Games - Suzanne Collins, The House of the Scorpion - Nancy Farmer, A Great and Terrible Beauty (series) - Libba Bray, Leviathan - Scott Westerfeld (its vaguely fantasy, but really good so you should read it), Eragon - Christopher Paolini, Feed - M. T. Anderson, The Singng (series) - Allison Croggon, and City of Bones (series) - Cassandra Clare (it has a couple vampires in it, but only in passing).
Some of those are a bit on the sci-fi side of fantasy, but there all really good. Hope this helps!
The Bartimaeus Trilogy by Jonathan Stroud. This is basically what I read as a teen (well, younger teen. I don't read books specifically marketed to teens very often, so here's what I got). It's about an alternate UK where all the politicians obtain power and influence by summoning demons for protection, or to carry out nasty human-rights violations, and general skullduggery. It's an interesting read, and I've given a terrible summary of the premise, but the books are quite good. A lot of that British humor, y'know.
Also. Christopher Moore is a brilliant author who doesn't work specifically within fantasy, but he has some great books like A Dirty Job (Type-B dude becomes Grim Reaper), Fluke (marine biologists trying to solve a mystery and really, it's like Fight Club. You can't say anything without giving it away), Coyote (totally irreverent and hilarious look at spirituality and the role of god), The Stupidest Angel (zombies on Christmas Eve), and other such fantasticity.
