So she ran out and bought The Salt Path.

She didn't much like the book, but a few weeks later, John picked it up.

Back in the world of Rainer Wynne's books, it's 2019 and Moth's been getting gradually sicker and sicker.

The sedentary lifestyle in Cornwall is hurting him.

But then, that summer, the couple plan a walking holiday in Iceland.

And before long, Raina's struggling to keep up with him.

But when the walk's over, they can't sustain his health.

It's the same pattern being repeated in all her books.

Moths ill, they walk, he recovers.

He keeps yo-yoing in and out of wellness.

And then in her third book, she becomes even more categorical about the medical miracle.

Landlines opens on Moth in crisis.

They've been living on Hay Farm and his health's worse than ever.

He's falling over and suffering incontinence.

They go to the doctor and it's bad news.

Raina's love for him won't allow her to accept his inevitable death.

She persuades him to go on one last hike, this time from Scotland all the way down to Cornwall.

It's their toughest walk yet, but it's worth it because when they visit the doctor again and have another brain scan, they get a totally different picture.

This time round, there's no sign of CBD in his brain.

It's been reversed.
