What is the author's message about home?

In Chapter Fifteen, An-mei and Lindo found a fortune that would tell Tin that Lindo wanted to marry him; it said: "A house is not home when a spouse is not at home." They were married and had Winston (who died in a car accident at age sixteen) and Vincent. Lindo had named both of them with names that sounded lucky: "Wins ton" and "Wins cent." When Waverly was born, she wanted her to have everything she had never had. She named her after their street with a twofold intention; Waverly should feel like she belonged in America just as much as their street, and when she left, she would take a piece of the place and her mother with her.
