A rather heavy going tale of making one's way in the world plows its furrows in the lobsterman's sea and on Lee's Island just off the Maine coast. At 16, Linn Robertson is the sole ward of a tyrannical Grandpa whose do's and don'ts go to the extent of forcing Linn to hand over every cent of his small earnings. Anxious to make a success of his trapping and fishing, Linn begins to stand up to Grandpa by buying a boat on the installment plan. The venture is promising but matters worsen when a rivalry develops and Linn is falsely accused of a misdemeanor. To clear himself he must make the decision to leave Grandpa and when he does, we find that the old man was only testing Linn all along to see how much he could take. The story ends on a new note of successful mutual understanding but readers will be short-changed on a sounder explanation of Grandpa's caprices.
