Caleb heads to the Arctic north on a large icebound wooden sailing ship. The island is permanently icebound, and its northwestern coast faces onto the open Arctic Ocean. While icebound, the crew spots two dog sleds, one chasing the other. Jackets include; Matt, Hesper, Dover, Thronridge and Icebound. But he found this route was dangerously icebound, and also too shallow for commercial travel. Its story continues from where the previous book, "The Icebound Land", ended. This plan was frustrated, as "Discovery" remained firmly icebound. "The Icebound Land" was well received by reviewers. Pyasino freezes up in October and stays icebound until June. "Icebound" won the 1923 Pulitzer Prize for Drama. It freezes up in late September and stays icebound until June.
