John Green and Veronica Roth joined J.K. Rowling on this year’s Forbes’ Celebrity 100 list.
The Celebrity 100 list measures earnings and fame to rank the 100 most powerful and popular personalities within multiple pop culture categories, including film and books.
Green and Roth collectively sold 8.5 million copies in 2013. Their success has been cited by researchers to the recent boom of interest around the YA category.
Roth, at 25, is one of the youngest additions to the list.
