HarperCollins Publishers announced Monday the acquisition of a two-book deal by international bestselling author Veronica Roth, author of the Divergent series.

Joanna Volpe sold World English rights on behalf of Newleaf Literary to Katherine Tegen, Vice President and Publisher of her eponymous imprint at HarperCollins Children’s Books.

In the untitled first novel of a duology in the vein of Star Wars, Veronica Roth explores—with poise and poignancy—the story of a boy who forms an unlikely alliance with an enemy.

Both desperate to escape their oppressive lives, they help each other attain what they most desire: for one, redemption, and the other, revenge. Roth commented, “I’m really enjoying working on this new series. I can’t wait to share it with readers!”

The first of Veronica Roth’s upcoming young adult novels will publish in 2017, with the next novel to follow in 2018.

Veronica Roth is the author of DIVERGENT series, with over 32 million copies sold.
