“It is good you have each other, the artist had said, regarding them
seriously as she worked. You never have to explain yourself to sisters.
It was true. Being one of four sisters always felt like being part of
something magic. Once Bonnie noticed it, she saw the world was made up
of fours. The seasons. The elements. The points on a compass. Four suits in
a pack of cards. Four chambers of a human heart. Bonnie loved being a part
of this mystical number, this perfect symmetry of two sets of two.”
