[Scroll up 7% from the bottom] Just before he died, my grandfather wrote a slim little book called “Last Boat to New York,” which laid out, in typically sparse nordic prose, the mechanics of his unlikely escape to the USA. I’ve read and reread the book many times, each time hungry for answers that aren’t on the page. Even if it lingered on the practical details of how much bread they packed or how they managed to reef the sails in a full gale, the book did not address the man inside the boat nor did it really mine the complex relationship that he maintained with his homeland.
