Beginner’s pluck: Karin Walker’s brilliant summer read

Karin Walker wrote her book in 2007 before updating it a year ago: 'I updated the novel and submitted it again. I now have a three-book deal.'
Karin didn’t read as a child but, as a teenager, she became a “list fanatic”.
“They became more than lists,” she says. “I was emptying my head onto my Filofax. It was my outlet.”
