Erin Hunter is the Pen Name of the four authors (Victoria Holmes, Kate Cary, Cherith Baldry and Tui Sutherland) of the Warrior Cats and Seeker Bears series, and is also being used by a new author, Gillian Philip, who is writing the Survivors series. The authors (excluding Tui who lives in America) are British, and were asked to write the Warriors series by HarperCollins. So far, over fifty books have been released under the Erin Hunter name, proving to be quite a success. The name "Erin Hunter" was created by the publisher: "Erin" is a Celtic name to reflect the series' setting, and "Hunter" to emphasize the theme of wilderness - and to put the books on the shelf near Brian Jacques' Redwall series.
Vicky Holmes: The "boss" Erin. She is the one that came up with the plots and storylines for Warrior Cats and Seeker Bears, and she edits the two series, in addition to having written three of the Field Guides on her own. Many of the decisions about the plot rest with her, though she doesn't always get her way. As the "face" of Erin Hunter, she's the one who writes author's notes and goes on tours. Vicky lives in the UK with her husband, Richard, along with several sheep, a horse, and her dog, Missy. She has written a couple other books of her own, called Rider in the Dark, The Horse from the Sea, and Heart of Fire. Her Facebook page can be found here.
