‘It was believed lightning would not strike a house that held a thunderstone. And so these fossils were placed on top of clocks, under floorboards, over stable doors… But there are some storms that thunderstones cannot prevent.’

In the wake of a traumatic lockdown, Nancy Campbell buys an old caravan and drives it into a strip of neglected woodland between a canal and railway. It is the first home she has ever owned. It will not move again.

As summer begins, Nancy embraces the challenge of how to live well in a space in which possessions and emotions often threaten to tumble. She masters the van’s mysterious mechanics, but as empty passenger trains rumble past inches from the windows, rain and grief threaten to flood in.

Yet soon, Nancy’s encounters with the community of boaters moored nearby, and their lessons in survival off-grid, prove fundamental. The wasteland burgeons into a place of wild beauty, as Nancy works to clear industrial junk and create a forest garden. And as illness and uncertainty loom once more, it is these unconventional relationships, this anchored van, that will bring her solace and hope.

An intimate journal across the span of a defining summer, Thunderstone is a celebration of transformation; an invitation to approach life with imagination and to embrace change bravely.
