I have studied CST for three years and found the first time I read this book to be the most scary thing ever, and that I would never be able to understand the very detailed graphic breakdowns of the cranial anatomy, but if you sit back and view it little by little using your course notes too you realise the genius of the way it is constucted so you can use it as a reference all the way through your training. So it is one book for everything!! Money well spent and education well constructed well done Dr John!
