I think I may have read all the good ones written by SK. Because this one was awful. Well, not really. It would have been good if it wasn't for "ghost" Sadie.
I hated her, intensely. She behaved like a spoiled girl the entire book. Her shouts made my head hurt. It was like she was shouting in my ear. If it wasn't her stupid necklace it was Lara's clothes. Or Ed. Or dancing. I can't say which one was worst: necklace, Ed, dancing. Multiply that by a hundred and you will get Sadie's demands. And no, she wasn't funny AT ALL.
I had to scan-read the last chapters cuz I just couldn't take her anymore. Gosh, her whinny voice. Strident noise for my ears.
SHUT THE HELL UP SADIE, AND GO AWAY!
