Same as last year's...Captain Underpants.
Just as in 2012, the potty humor of the Captain Underpants series by Dav Pilkey brought the books to the top of the list. Other repeat offenders in the top ten included Sherman Alexie’s The Absolutely True Diary of a Part-Time Indian, Fifty Shades of Grey by E.L. James and Looking for Alaska by John Green. The newcomers to the top ten were:
The Bluest Eye, by Toni Morrison (second place)
The Hunger Games, by Suzanne Collins
A Bad Boy Can Be Good for A Girl, by Tanya Lee Stone
The Perks of Being a Wallflower, by Stephen Chbosky
Bless Me Ultima, by Rudolfo Anaya
Bone (series), by Jeff Smith
