Why does Lily faint?

This occurs in Chapter 6. After the story, the Daughters begin dancing, and then each of them slowly walks up to the statue of Mary to touch her heart. Lily is compelled to do the same, so she rises and walks toward Mary to touch her heart. As she does so, June stops playing the cello, and Lily realizes that she is not included in the ritual. August scolds June for her inhospitality, and Lily faints.

Lily wakes up in August’s room after the meeting of the Daughters. Everyone attributes Lily’s fainting to the heat of the day. You can check it out at the GradeSaver link below,
