Erin Hunter is actually four people! She is experienced children's authors Kate Cary, Cherith Baldry, Victoria Holmes and Tui Sutherland. Vicky comes up with the story ideas and makes sure the books stay consistent, and Kate, Cherith and Tui take turns writing the books. They came up with the single name, Erin Hunter, to avoid confusing their readers by having books from the same series filed in different places on the bookshelves.

Erin's popular Warriors series keeps readers coming back with tales of territories, clans and cats. In the recently released The Last Hope, the mysterious and prophesied fourth warrior finally appears…or does he?
