I want to inform you that the summary on Peace like a River will not be short. Here is the paragraph I managed to find. One part Christian-inflected odyssey, one part tragedy, and one part classic adventure in the American West, Peace Like a River by Leif Enger is the story of a 1960s Minnesota family narrated by the asthmatic Reuben, the product of the first of his father’s seven miracles. The title takes its name from the Christian hymn “It Is Well With My Soul” In case, you feel like this is not enough, I want you to check what the writers from Prime Writings can do for you.
What do you need help on?
