I have abandoned this book for the third time now, and it is probably time for me to finally give up. While I understand why certain aspects of "Obsidian" might attract certain readers, Katy and I will never get along with each other, and neither will Daemon and I. There is a huge difference between characters which are so annoying they seem realistic, and characters which are so annoying that you wouldn't care less if they died in an accident.
