THIS is an immensely moving, intensely intimate memoir in the form of a love letter from the author to Ruth France, a social worker who was swept to her death in a raging South Lakeland river.

It is also a brave, seeringly honest portrayal of a relationship that, for the most part, defied definition.

Mr Pepper’s prose is sometimes slow like a waltz and at other times as taut as a tango; but always moving.

The author, an award-winning nature writer, has produced a hauntingly tender love story that reveals the true and often evasive nature of love.
