The Welsh landscape plays a pivotal role in the book, becoming a character itself, says Balding.
She added she and Sue Butler did lots of walking in the area to help her try and bring the land and hills to life in the novel.
She also spent time with Colin and Tracey Evans, local farmers in Monmouthshire, so she could describe accurately the demands of the industry and issues faced by people living in the countryside.
“I hope it reflects how difficult farming life is and how much we should value farmers and what they do to protect our landscape. Also how hard they work, that things are always going wrong on farms and you’re constantly firefighting.
“It’s really, really hard for anyone to breakeven, let alone make money. So how do you do that if you’re not Jeremy Clarkson, coming in with millions already?”
Balding said she also wanted the book to celebrate Welsh community spirit and kindness.
“People help each other out. I think that’s particularly true in rural communities.
“It’s almost like a tribute to friendship and what people do for you, when you need it most, without you even asking.”
