Why does Violet visit Our Lady of Mount Carmel Monastery in the novel, All the Bright Places?

Our Lady of Mount Carmel Monastery is one of the last places Violet visits in her attempt to follow Finch’s last steps. It is at this monastery that Finch has left the gray rock that he gave her when they started their wanderings. The rock is left in the hand of Jesus, perhaps a message to Violet she needs to leave her troubles, future and plans in the hands of a higher power.
