Erin Hunter
In the year 2003, HarperCollins asked Victoria Holmes to write a fantasy series about feral cats, but, not being a reader of fantasy, she was less than enthusiastic, despite her love of cats. After writing one storyline, Kate Cary was brought in to write the book as Holmes went behind the scenes to supervise details and edit the book. Then, on the third book, "Forest of Secrets", Cherith Baldry joined Erin Hunter. Later, after Sutherland wrote the first "Warriors" field guide, she became the fourth Erin Hunter.
