Grim Tuesday

Seven days. Seven keys. Seven virtues. Seven sins. One mysterious house is the doorway to a very mysterious world—where one boy is about to venture and unlock a number of fantastical secrets. Arthur doesn't think he will ever 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—in the form of an enemy named 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, surviving a very weird work camp, befriending a bear-like spirit, fighting the void-like Nithlings, and traveling in the scary Far Reaches for the ultimate showdown.
