Yes, the book is very different to the show, not just in the course it takes but in tone too. Aunt Lydia in the book is a a horrible person who seduced her brother in law, and the book is full of dark sexual undertones of sex clubs and 'machines' in Dr Eliott's office for somem kind of deviant sexual behaviour! Even Jack is a visitor of one of the clubs, it's very.....different. Very very different.

I do wish Molly had stayed longer though, maybe up until they opened the House of Eliott or at least as a guest star now and then. The actress played her pefectly I thought.
