Some possible choices include:
Carolyn Mackler's newest, "Tangled"
Suzanne Young's debut, "The Naughty List"
Francisco X. Stork's "The Last Summer of the Death Warriors" (I know it is shallow to love a book for its cover, but the Stork covers always thrill me -- and the innards live up to their outer beauty)
John Green and David Levithan's "Will Grayson, Will Grayson"
Printz winner "Going Bovine" by Libba Bray
And Printz honor winner "The Disreputable History of Frankie Landau-Banks" by E. Lockhart
