"Arthur Penhaligon didn't think he would have to return to the very strange house that nearly killed him on Monday -- and 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."--P. [4] of cover.
