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.

Before she went to join Sam and Mogget downstairs, Lirael paused for a moment to look at herself in the tall silver mirror that hung on the wall of her room. The image that faced her bore little resemblance to the Second Assistant Librarian of the Clayr. She saw a warlike and grim young woman, dark hair bound back with a silver cord rather than hanging free to disguise her face. She no longer wore her librarian's waistcoat, and she had a long Nehima at her side rather than a library-issue dagger.

Lirael has never felt like a true daughter of the Clayr. Abandoned by her mother, ignorant of her father's identity, Lirael resembles no one else in her large extended family living in the Clayr's glacier. She doesn't even have the Sight, the ability to See into the present and possibly futures, that is the very birthright of the Clayr.
