After reading the Hunger Games, I went through a "YA Distopian Trilogy" phase. I've read a ton of them! My favorites (these include only the series where I liked all three books. I won't list Divergent, because while I loved the first book, the series went downhill from there):
Daughter of Smoke and Bone, Laini Taylor
Under the a Never Sky, Veronica Rossi
Girl of Fire and Thorns, Rae Carlson
Razorland Series, Anne Aguirre
Series that still have books coming out:
The Lunar Chronicles, Marissa Meyer
The Dust Lands Series, Moira Young
Penryn and the End of Days, Susan Ee
Not really Distopian, more "Other Worldly":
Shadowfell, Juliette Marillier
Graceling, Kristin Cashore
Adult Series:
Outlander
A Discovery of Witches
Clan of the Cave Bear (except the last one)
