Moonrise is a children's fantasy novel, the second book in the "" series. The book, which illustrates the adventures of four groups of wild cats (called Clans), was written by Erin Hunter (a pseudonym used by Victoria Holmes, Cherith Baldry, Kate Cary, and Tui T. Sutherland), with cover art by Wayne McLoughlin. "Moonrise" follows six cats, Brambleclaw, Squirrelpaw, Crowpaw, Feathertail, Stormfur, and Tawnypelt, as they return to their forest home from a journey to the ocean. They travel through the mountains, where they meet the Tribe of Rushing Water, a new group of cats first introduced in this novel. The Tribe cats are being attacked by a savage mountain lion called Sharptooth. The Clan cats eventually agree to help the Tribe get rid of Sharptooth. Series editor Victoria Holmes drew inspiration from locations such as the New Forest and the Scottish Highlands.
