What is the importance of the Lewis House in the novel, Wench?

The Lewis House is the vacation resort for freed blacks that live in the North. Although it is a resort, it is not nearly as fancy as the Tawawa House. Still, just the idea of a resort for blacks - who don't have to think about work - who have servants of their own to wait on them, excites the slaves at the Tawawa House. Inside the Lewis House is a small library and a piano, two objects that tickle Lizzie's fantasies for her own children's futures. While most of the slaves are happy just to imagine this place, Mawu is determined to visit it. When Mawu runs away from Tip in the final section of the novel, it is safe to assume that she met up with freed blacks at the Lewis House to aid her escape.
