How does the author use foreshadowing in State of Wonder?

Chapter 1 introduces several major concepts and themes, as well as characters, that are used throughout the novel. First, the death of Anders Eckman is immediately introduced, setting the stage for the mystery part of the storyline. It is clear from the letter of Dr. Swenson that something is awry, in that she sends no body nor possessions. This foreshadows both Karen Eckman's questions about her husband's death as well as the discoveries at the end of the novel that Anders isnot, in fact, dead. Through the announcement of Anders' death, readers also begin to see the queer nature of the relationship between Fox and Marina. Clearly, they care for one another in a romantic way, but Fox already shows a lack of emotional capability in this chapter, setting the stage for his behavior throughout the novel. Marina, in this chapter is introduced as a logical, caring, determined woman who cares about those around her, and tries to please them. These traits, along with her own reaction to the death, foreshadow her role as the person to go to Brazil in search of the truth.
