Lorna Russell, editorial director at BBC Books, has acquired Adam Henson's memoir Like Farmer, Like Son for publication in June.
Russell bought UK and British Commonwealth rights from Gordon Wise at Curtis Brown.
Henson's work on his Cotswolds farm is featured in a weekly segment on BBC1's "Countryfile". Like Farmer, Like Son will explore "a hidden family history and the unbreakable bond between Adam and his life-long hero: his father Joe."
Henson said: "The story of my life has mirrored my father's to a quite uncanny degree. Right from when I was a little boy, he was my rock; my mentor; my hero. It is no exaggeration to say that he taught me virtually everything I know about both country life and television. Without him, I certainly would not be doing what I am today."
Henson's father Joe, who died last autumn, overcame a serious stammer to become a regular TV broadcaster on country matters, as well as becoming the saviour of Britain's rare breeds and opening the world's first Farm Park.
Like Father, Like Son will include "treasured family photographs" and trace "the ups and downs in the lives of three generations of Henson men and how their relationships helped and hindered them."
