How does the author use foreshadowing in the novel, Whistle Me Home?

The opening scene effectively sets up the novel's conflict, explaining that Noli and TJ have been separated for five months and two days; the reader continues, knowing that these two will break up in the course of the story, but not knowing the circumstances. Other examples of foreshadowing in the novel include moments in which TJ's past is hinted at, but not revealed. The best example is the New Year's Day scene in New York City.
