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 has kept readers coming back with tales of territories, clans and cats. Book 1 of the brand new Survivors series, The Empty City, promises more of the same, except that dogs take the lead. In Book 1, in the aftermath of the Big Growl that destroyed his city, a Lone Dog named Lucky must find a way to work with other dogs in order to survive in this frightening new world.
