Erin Hunter (edit name/settings)

Erin Hunter is the pen name of four authors: Cherith Baldry, Tui Sutherland, Kate Cary, and Victoria Holmes. They chose to use one pseudonym so all their books would be shelved in one place. They are the authors of two series: Warriors, which is about clans of wild cats, and Seekers, which is about the adventures of four bear cubs.

Authors

VICTORIA HOLMES
Holmes was the original author of the series with HarperCollins requesting her to write the series. After inviting Kate Cary to do the actual writing of the book, she moved behind the scenes to help edit and supervise the details.
Holmes grew up on a farm in England. She was born on the July 7, 1974, and learned how to ride horses at two. Later she attended Oxford University. There, the buildings "inspired an interest in history". She now lives in London where she works as the editor for the series.
On April 5th, 2011, Bookperk, a site that offers special deals on books, ran a special for signed copies of Warriors: Omen of the Stars #4: Sign of the Moon. Because Erin Hunter is not an actual person, these books were signed by Victoria Holmes on behalf of the created persona.

KATE CARY
Kate was the second author brought on board to write for the series. Holmes chose Cary to write the first book after Holmes had finished one storyline. In the first series she wrote Into the Wild, Fire and Ice and Rising Storm. In the second series she only wrote Dawn, the third book. In the third series she wrote The Sight, Dark River and Eclipse. In the most recent series she wrote Fading Echoes.
She was born in England on November 4, 1967. She later moved to Scotland where she lived for 12 years before going back to England where she currently resides. Besides the Warriors series she has also written the books Bloodline and the sequel Reckoning.

CHERITH BALDRY
Cherith was the third author brought in to the Erin Hunter team. Holmes invited her to join on the third book, Forest of Secrets after seeing her writing style feeling that it was similar to Erin Hunter's.

TUI SUTHERLAND
Sutherland was born in Caracas, Venezuela, but now lives in the United States which makes her the only non-British author of the series. She now lives in Boston and first wrote the field guide Secrets of the Clans.

Each of the Erin Hunters, not surprisingly, grew up with animals.
