Massive thanks are due to everyone who has helped me get this book from the initial ideas to the final draft and the written page. I would like to firstly thank Lydia De Cruz, Commissioning Editor, for supporting me from the concept stage to the short Routledge book fruition, and for taking a risk with me. Many thanks also to Arunima Aditya for keeping me on track and answering all my questions. Special thanks to Dr Wendy Laverick and Bee Rowlatt as well as Jess and Jack for reading and commenting on the early proposals and providing me and the publisher with feedback. Special thanks to Dr Alison Jarvis for the help you gave me with the tables in Chapter 3. You are a star! Many thanks to Bee Rowlatt and Dr Wendy Laverick for also reading the first draft and feeling able to provide an endorsement of this work. I really appreciate this.
