How long did it take Jacob and his dad to arrive on the island?

It took Jacob thirty-six hours to get to the island.

It was colder and wetter than I’d ever known June could be. I hoped, for his sake and mine, that the grueling thirty-six hours we’d braved to get this far — three airplanes, two layovers, shift-napping in grubby train stations, and now this interminable gut-churning ferry ride — would pay off. Then my father shouted, “Look!” and I raised my head to see a towering mountain of rock emerge from the blank canvas before us.

It was my grandfather’s island.
