"sold" climax

i believe the climax of sold is when lakshmi gets sold to the whore house and has to work for mumtaz to pay off her debt to her.in that part of the story her life drasticly changes for her and goes down hill. each and every day she has customers constantly do what they want to her like she isnt even human,but instead they treat her like an object for sex.she is always mistreated and abused and raped but she cannot really do anything about it really at this point.after shes been there for awhile an american shows up and offers her to get taken away to a clean place away from the whore house and after mumtaz gets arrested later in the book that wish happens for her and the other girls.
