Erin Hunter is a shared pen name used by a rotating group of authors — including Victoria Holmes, Kate Cary, and Cherith Baldry — to produce animal-fantasy fiction for young readers. The name is best known for the Warriors saga, a long-running series following clans of wild cats, as well as related spin-off arcs such as The New Prophecy and Power of Three. Holmes typically drives the overarching plots while the other writers take turns crafting individual books in the series.
