Books similar to Hunger Games

To avoid doing homework, I helped a former library boss but still a great friend to find books that are similar to Hunger Games by Suzanne Collins. I found about 12-15 books and thought to share it with everyone else in case you have just read or want to read other books that have the same qualities of Hunger Games, but don't want to re-read the books (But, come 'on, who wouldn't want to re-read them?!)

So, here's a list of the books and I'm linking the title to Goodreads so you can get a better sense of what the books are about. These aren't in any particular order, just the books that came to me throughout the night.

Enclave by Anne Aguirre

Girl in the Arena by Lise Haines

Incarceron by Catherine Fisher

Glow by Amy Kathleen Ryan

Rot & Ruin by Jonathan Maberry

Unwind by Neal Shusterman

Uglies series by Scott Westerfeld

Divergent by Veronica Roth

XVI by Julia Karr

Blood Red Road by Moira Young

The Running Man by Stephen King

Delirium by Lauren Oliver

Eden by Keary Taylor

So, what do you think? Anything look interesting to you? I've read Delirium, the Uglies series, and Girl in the Arena and they all have similar qualities as Hunger Games. I'm really interested to read Enclave, Divergent, and Eden, though. They look really intriguing!
