I wanted to give it more. I really did.
I liked Kat. She is a strong female character that is both tough and resourceful without being a bitch. She didn't take any crap and walked when she realised she wouldn't get what she needed from Darkness.
My problem was with Darkness. He was a dick for most of the book. Actions speak louder than words true, but his actions gave me whiplash. Part of me was cheering Kat on as she walked away.
