Guardians of the Lost by Margaret Weis and Tracy Hickman

For two centuries the portion of the great Sovereign Stone belonging to the humans of Loerem was lost from sight and memory. But there are those who dare never to forget...

A magical relic has been miraculously recovered -- and the battle for the future of Loerem begins. It is a nightmare conflict that will ensnare dwarf, human, elf, and orken beings, as the immortal dark lord Dagnarus launches terrible war from the blackest depths of the Void. And now heros must emerge from the most unlikely corners of the world to deny Dagnarus the awesome power of the Stone -- or suffer the hideous damnation of his hellish reign.

Divergent by Veronica Roth

In Beatrice Prior’s dystopian Chicago world, society is divided into five factions, each dedicated to the cultivation of a particular virtue—Candor (the honest), Abnegation (the selfless), Dauntless (the brave), Amity (the peaceful), and Erudite (the intelligent). On an appointed day of every year, all sixteen-year-olds must select the faction to which they will devote the rest of their lives. For Beatrice, the decision is between staying with her family and being who she really is—she can’t have both. So she makes a choice that surprises everyone, including herself.

During the highly competitive initiation that follows, Beatrice renames herself Tris and struggles alongside her fellow initiates to live out the choice they have made. Together they must undergo extreme physical tests of endurance and intense psychological simulations, some with devastating consequences. As initiation transforms them all, Tris must determine who her friends really are—and where, exactly, a romance with a sometimes fascinating, sometimes exasperating boy fits into the life she's chosen. But Tris also has a secret, one she's kept hidden from everyone because she's been warned it can mean death. And as she discovers unrest and growing conflict that threaten to unravel her seemingly perfect society, she also learns that her secret might help her save those she loves . . . or it might destroy her.

Debut author Veronica Roth bursts onto the YA scene with the first book in the Divergent series—dystopian thrillers filled with electrifying decisions, heartbreaking betrayals, stunning consequences, and unexpected romance.
