I'd like to thank everyone at Capstone, my commissioning editor Holly Bennion and Vicky Kinsman who believed in the project and guided it on its way, Jenny Ng, my wise and patient Development Editor, Production Editor Tessa Allen and all the marketing and sales teams.

I'd also like to thank my supportive family and the good friends with whom I've discussed this huge topic over the years. I'm lucky to have you all in my life.
