Drowned Wednesday

This is Book Three in Garth Nix’s blockbuster fantasy-adventure series, The Keys to the Kingdom, following the best-selling Mister Monday and Grim Tuesday.
Arthur Penhaligon has a broken leg, bad asthma, and an invitation he can’t refuse. There’s no time for rest and recovery, Drowned Wednesday has sent a ship to pluck Arthur from his comfortable bed, miles from any ocean, and sail him back to the House.
From hospital room to the high seas, Arthur finds himself on an adventure that will pit him against pirates, storms, explosions of Nothing-laced gunpowder, and a vast beast that eats everything it encounters. Through it all, he is drawn deeper into the mystery of the Architect’s disappearance, and the plotting of the Trustees. For the sake of all that dwell in the Secondary realms, Arthur must discover the third part of the Will and claim the Third Key.
But first he has to survive life aboard ship on the Border Sea . . .
Another breath-taking mix of magic, mystery, adventure, humour and excitement from Garth Nix.
