Erin Hunter is a collective pseudonym used by the authors Kate Cary, Cherith Baldry, Gillian Philip, Inbali Iserles, Quincey Schwab, and Tui T. Sutherland, along with editor Victoria Holmes, in the writing of the Warriors, Seekers and Survivors book series. Each of the authors play a different role: while Holmes creates the storyline of each book, Cary, Baldry, Schwab, and Sutherland take turns writing the books. In addition, another person who is not an Erin Hunter writes the manga: Dan Jolley. The newest addition to the group is Inbali Iserles, who writes Survivors under the pseudonym as well.
