What does Ola plan to leave Emily upon her death in the novel, Toning the Sweep?

From the text:

"I will dream of the desert forever; it will never leave me. Ola says that it doesn't have to. She says the house in Little Rock is mine to come to whenever I want. That won't be for years, though, because she's never coming back to it. I know I can't come back to it while she's alive."
