Kelly knew at once that the half-vampire did not believe her.
"I'm not an idiot, you know," she said. "And anyway, I can't read."
"Sorry, but you can't read? Seriously?" Kelly realized how conflicting her previous statements had been - "I'm not an idot" and "I can't read."
"No, I can't. Get over it." Kelly licked her lips and spoke bravely.
"I don't know how to stop you craving anything at all, but I can stop you from craving blood." She paused. "You have to turn your cravings onto something else. It was in a book my mother read to me when I was younger. By Terry Pratchett. One of them made himself crave coffee. Bad idea, because then when the coffee ran out ... but the other one made himself crave something else. Can't remember what it was called but it was 'being addicted to taking photographs'. So then he didn't hurt anyone ..."
Kelly tailed off as she realised that Gabby really was not listening.

"How do you know?" she asked.
"Because," said Kelly bravely, "my brother is a vampire."
