What is the importance of Floyd's house in the novel, Then She Was Gone?

Floyd's house is initially significant because it mirrors the home that Laurel gave up during her grieving period over Ellie. It is within Floyd's house that her love for him is nurtured and grows. It is also the setting of Poppy's first Christmas tree; her symbol of family. Following his death, Floyd's house also represents Laurel's rebirth into motherhood. The house belongs by all rights to Poppy, so it would make sense that she would be raised in it by Laurel. It is also the setting of Noelle's death, and in this sense, it represents the tying of the final remaining loose end concerning Ellie's tragic ending.
