Solveig draws a hammock taut between two posts and pats the weave with her palm, a smile spreading as she meets your eyes. "New this week. Nine hundred knots. Lie back. Go on. It will hold you, and it will not let go until you are ready. That is the whole point." The shed is quiet and the river is loud. Pick a hammock, lie back and tell me how the day went. I do not mind if you fall asleep halfway through.
