The third in the SPIRIT ANIMALS fantasy series about children and their spirit animals fighting to save their kingdom. Four children separated by vast distances all undergo the same ritual, watched by cloaked strangers. Four flashes of light erupt, and from them emerge the unmistakable shapes of incredible beasts — a wolf, a leopard, a panda, a falcon. Suddenly the paths of these children — and the world — have been changed for ever. Part engrossing book series, part action role-playing game — discover your spirit animal and join the adventure.

Get ready for more brilliant page-turning fantasy from master, Garth Nix. On the fourth day, there was war! Pick up with Arthur Penhaligon as his Keys to the Kingdom adventures continue in the mysterious House. Following their adventures in the Border Sea, Arthur and Leaf head for home. But only Leaf gets through the Front Door. Arthur is blocked because someone — or something — has assumed his identity and is taking over his life. Before Arthur can take action, he is drafted by Sir Thursday and forced to join the Glorious Army of the Architect. The Army has its headquarters in the Great Maze, a defensive area of the House. Half of the Maze has already been dissolved by Nothing, and hordes of Nithlings emerge regularly to attack the rest. If the Nithling invasion can overcome the Army and the Great Maze, the House will be lost and the whole universe with it. While Leaf tries to banish Arthur's doppelganger on earth, Arthur must survive his basic training, avoid getting posted to the Front and work out how he can free Part Four of the Will and gain the Fourth Key from Sir Thursday. If the latest, strongest and most dangerous Nithling offensive doesn't break through first!

Second title in Garth Nix's gripping new fantasy adventure series. Arthur Penhaligon didn't think he would ever have to return to the strange house that nearly killed him on Monday — the house that contains a fantastical and sinister realm inside. But the next day brings new challenges — in the form of an enemy named Grim Tuesday, who threatens the safety of both Arthur's family and his world. Arthur must retrieve the Second Key from Grim Tuesday in order to save everything — an adventure that will force him to steal a Sunship, survive a very weird work camp, befriend a bearlike spirit and fight the void Nithlings. Even after all that, he will still have to venture into the scary Far Reaches for an ultimate showdown.
