In the sixth and final book of the series, Ishmael Wang finds himself, through a series of somewhat contrived circumstances, owner of his own small passenger and cargo ship. He must now turn a profit for himself. An added wrinkle is that one of the crewmen is the heir to the shipping line where he used to work. She has been forced by a codicil in her father’s will to work as a crewmember for a year in order to inherit the company. This adds some unexpected complications.
While most of the book follows the same adventures in normality model as the previous ones, there is a healthy dose  of intrigue, and even some violence, in this last book. Ishmael’s final fate is bittersweet. While part of me wants to applaud Mr. Lowell for not giving our hero a stereotypical feelgood happy ending, part of me wishes he had.
