THE WRITER WHO MOST INSPIRED ISABEL

I loved Andrea Ashworth’s memoir Once in a House on Fire and wish I had found it years earlier.

HOW ISABEL BECAME KATE’S CLIENT

Once I had more than a hundred books to my name, I realised that the services of an agent could help me focus more time on what I really love – writing and speaking engagements. But I wavered for several years, and after meetings with other agents, because it always felt so difficult to invite another person into an established career. When I met Kate, those worries finally disappeared. She is warm, funny and passionate about such a diverse range of genres. Most importantly, I felt I would be proud to have her represent me.

KATE ON ISABEL

Isabel’s factual writing for children is breath-taking, beautiful and original and the sheer range of topics she can master is astonishing. Her knowledge, creativity and passion for science, biography and natural history are highly infectious. And on a personal level, we really click, which makes representing Isabel a complete and utter pleasure. I’m so proud she chose me to be her agent.
