Quill Tree Books publishes books for children and teens in all genres. Under the leadership of Vice President/Publisher Rosemary Brosnan, the imprint’s mission is to publish literary, award-winning books with wide appeal. We provide a platform for creators with a strong point of view, including those with underrepresented, authentic voices. The team publishes talented, award-winning authors such as Elizabeth Acevedo, Jerry Craft, Adam Silvera, Saadia Faruqi, and ND Stevenson, as well as bestselling authors whose books have gone on to become classics, such as Neal Shusterman, Gail Carson Levine, and Rita Williams-Garcia. Additionally, the team continues to publish an evergreen backlist of books from beloved authors like Walter Dean Meyers, Katherine Paterson, E. B. White, and Beverly Cleary.
