'Lirael' by Garth Nix
The second book in 'the Abhorsen Chronicles' and takes place in the same place as the first book. Contrary to the first book, this one follows two new main characters, one of them being Lirael (the second is a secret!). While the first book is more or less stand-alone, this one is a definite cliffhanger.
