This is a different brand of the story-cycle.  Each story is an independent aspect of the protagonist’s life.  They’re presented to the reader at the same time (as separate chapters).  They eventually merge into one story later in the book.  Although the reader is eventually made aware that each of the stories is about the same person, this does not resolve the final conflict.

1.  The passenger in seat 32A flashes back to her childhood as she sits on the plane bound for Italy.  One of the flight attendants has a sister who works in the reservations call center.  They often chat about the unusual things that happen to them on flights and reservation stories respectively.  

2.  Florence writes the letters that are sent all over the world.  She writes only at night, but she chooses places that are at least 6 - 9 hours ahead of her in time because.  The time difference helps her letter writing.  She is fueled by the knowledge that it is daytime and imagines the recipient reading her letters in elaborate stereotypical settings.

3.  (use her nick name) is an awkward middle schooler who is adjusting to the move her family had recently made to Lamesa, TX.  The adjustment becomes more and more difficult as she faces the challenges of puberty and her recent diagnosis of astigmatism.  She draws into an awkward shell at school.  The stress of the move and being new kid with glasses at school starts to affect her sleep.  She grows terrified of the night and sleeps less and less.  And when she does get to sleep, she often sleepwalks around the house.  Her family didn’t pay any attention to it until the neighbors brought her home one night.  The stress is compounded again as she hears her mother and father argue over what to do about it.  Her father wants to take her to a psychiatrist, but her mother won’t have it.  She doesn’t trust doctors.  So her father secretly takes her to a psychiatrist in Lubbock.  Her mother (a fellow school teacher) insists that she start some extracurricular activities to help ease the adjustment.  She’ll meet new friends and have new social obligations that will keep her busy.  She’ll be so busy that she’ll have no choice but to fall asleep at the end of the day.

4.  Alethea in Egypt.
