There's this list that i got from the library for suggested teen reading, here it is-
ARTEMIS FOUL: THE LOST COLONY-(though i would suggest that you read the ones that come before in the series first, this one is the most recent; fantasy)
CHASING VERMEER-sort of childish version of the DaVinci Code.
NEW MOON-vampire/love/coming of age story, sequal to Twighlight
AIMEE-teenage friendship story, sad at first, but a VERY good book.
MY SISTER'S KEEPER-a great story not only telling about life as a teenager, but addressing the political and individual effects of tampering with genetics.
EMMA AND ME-very good, coming of age story about a girl's fight to survive in her own home.
ERAGON-dragon fantasy story, kinda slow but good.
there were more on the list, but i havent read them yet, so i cont tell you what they're about or of they're any good, but here they are:
City of Ember, Dragon Rider, Dragonspell, Flyte, Harry Potter and the Half-Blood Prince, High Rhulain, Knofe of Dreams, Lightning Thief, Marley and Me, Maximum Ride: The Angel Experiment, Peter and the Star Catchers, Ptolemy's Gate, The Rivers of Zadaa, Summer of the Apocalypse, The Truth about Forever, and Uglies (the second book in a 3 part series)
hope that this helps!
