Actually an author recommendation: Raynor Winn.
Her first book, a memoir, is The Salt Path. It's followed by The Wild Silence and the newest one is Landlines. [Not published yet in US but someone local purchased it in UK earlier this year and donated it to our library.]
I've read them all and find them incredibly engrossing, touching, and prescient.
Start with The Salt Path to understand what led her and her husband to walk the South West Coast Path in England.
