I've been asked to be a ghostwriter for two autobiographical books for the same person. One book will be a general life events type book and the other will focus on a particular aspect of their health that they want to shed light on in the hope that others with the same condition will find help and encouragement. I'm very keen to hear about any tips and tricks others have found from their own ghostwriting experiences - what kind of interview questions to ask, how often do you meet to review the work, anything else that would be helpful.
