But now Cath is back home in Connecticut, in the arms of her loving, if distant, husband Derek -- and watched over, perhaps a bit too closely, by her critical sister-in-law Yvonne. Informed by Yvonne that her mysterious disappearance was merely another symptom of her ongoing mental problems, Cath tries her hardest to piece together her fragmented memories and make sense of her sudden flight. But why, if she has always suffered from mental problems, can Cath not remember ever speaking with a therapist? Why, if she and Derek have always had a happy marriage, is Cath beginning to remember evidence of "other women" -- and to cast a suspicious eye on Derek's current aloofness? And -- most terrifying -- what happened to these other women? How much can Cath trust the vague terror that fills her memories -- terror that may have bought her a seat on a night bus to Florida?
