I have just bought it on Kindle and skimmed fairly thoroughly through it.
It starts with a section on the supposed science of ME, with lots of good quotes about it being a serious physical illness. Her attempt to explain the science makes sweeping statements about it all being to do with overactivity of the sympathetic nervous system, being stuck in 'flight or fight' mode, plus some rather vague stuff about mitochondria and genetics based on Myhill's research.
The author started with mild ME, was sent to an ME clinic psychologist who encouraged her to exercise, resulting in very severe ME for 2 years - bedbound, needing full time care. She then gradually 'recovered' and attributes this to a mix of her own determination, using deep relaxation, nutritional supplements and unspecified alternative therapies, and a good experience as an inpatient at an Essex clinic that no longer exists.
She uncritically recommends everything from Myhill, to Optimum Health Clinic to unspecified alternative medicine, to NHS ME clinics, listing these at the end without any caveats, despite describing her own disastrous experience.
She also seems to think that 'recovery' is the normal pattern provided you follow the sort of path she followed, though it's not clear how recovered she is. She uncritically says GET and CBT can be helpful for mild to moderate ME provided you don't push too hard.
On the positive side, she describes very severe ME well, and the level of care needed, and gives helpful advice for friends, carers, and to supporters of carers.
The sections on care are entirely based on the assumption that everyone with severe/very severe ME has loving family members who provide very high quality selfless 24 hour care as she was fortunate to have. She makes no mention of the fact that many people are not so fortunate to have that level of loving care.
The overall impression left is that ME can be a very severe illness for a couple of years, and that if you have the right support, and use the right treatments, you will recover.
