The river is the river (Broché)

A dazzlingly inventive novel that explores the whole nature of storytelling and writing. A woman called Naomi arrives at her sister's house, intending, it seems, to say goodbye. She is abandoning her city life for a remote Scottish retreat, which she will share with a man named Bernát, whom she considers some kind of visionary. In a sequence of stories filtered through multiple retellings, she illuminates the character of this elusive individual.
One story seems of special significance : about Afonso, an Amazon boatman, who could be the last speaker of his mother tongue, a language of apparently unique simplicity and precision. Bernát and Naomi are not, however, the only storytellers here. Naomi's sister, Kate, is herself working on a novel that begins as a ghost story, but ends up as something rather different : The river is the river.
