Happy House

Arthur doesn't think he'll have to return to the strange house that nearly killed him on Monday, the house that contains an entire world. But Tuesday brings new challenges: the enemy Grim Tuesday, who threatens the well-being 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 include stealing a Sunship, fighting the void-like Nithlings, and traveling in the scary Far Reaches for the ultimate showdown.

Arthur Penhaligan has wrestled five of the Keys from their immortal guardians, the Trustees of the Will. But gaining the Sixth Key poses a greater challenge than any he has faced before. Superior Saturday is not just one of the Trustees - she is also the oldest Denizen and the most powerful and knowledgeable sorcerer within the House.

Artemis is at boarding school in Ireland when he receives an urgent e-mail from Russia. In it is a plea from a man who has been kidnapped by the Russian Mafia: his father. As Artemis rushes to his rescue, he is stopped by a familiar nemesis, Captain Holly Short of the LEPrecon fairy police. But this time, instead of battling the fairies, he is going to have to join forces with them if he wants to save one of the few people in the world he loves.

Wednesday has rolled around, and Arthur Penhaligon has an invitation to return to the House that he can't refuse. Drowned Wednesday has sent a ship to pick him up from the hospital...even though his hometown is miles away from any ocean.
