This week's question: What were the most frequently challenged books of 2015?

Every year, the American Library Association's Office for Intellectual Freedom tallies reports of attempts to ban books from schools and libraries. Last week, they released the list of the top 10 most challenged books of 2015.

1) "Looking for Alaska" by John Green

Reasons challenged: Offensive language, sexually explicit, and unsuited for age group.

As the author of the bestselling "Fault in Our Stars" and "Paper Towns" — both of which have been adapted into films — Green is a young adult lit phenomenon. "Looking for Alaska," which will also be adapted into a film next year, tells the story of a boy who enrolls at a boarding school, and encounters a force-of-nature girl who lives down the hall.

2) "Fifty Shades of Grey" by E.L. James

Reasons challenged: Sexually explicit, unsuited to age group, and other ("poorly written," "concerns that a group of teenagers will want to try it").

James's erotic romance novel follows the steamy relationship between recent college grad Anastasia Steele and a wealthy and controlling young business man, Christian Grey.

3) "I Am Jazz" by Jessica Herthel and Jazz Jennings

Reasons challenged: Inaccurate, homosexuality, sex education, religious viewpoint, and unsuited for age group.

This illustrated children's book is based on the true story of Jazz Jennings, a transgender child who helped pen the story.

4) "Beyond Magenta: Transgender Teens Speak Out" by Susan Kuklin

Reasons challenged: Anti-family, offensive language, homosexuality, sex education, political viewpoint, religious viewpoint, unsuited for age group, and other ("wants to remove from collection to ward off complaints").
