Ann Brashares said this quote

Those were the people who made her something, and without them she was different. She'd held on to them and to that old self tenaciously, though. She clung to it, celebrated it, worshipped it even, instead of constructing a new grown-up life for herself. For years she'd been eating the cold crumbs left over from a great feast, living on them as though they could last her forever.
