What metaphors are used in Hush, Hush by Becca Fitzpatrick?

Metaphor:

"'Trust me, Dorth, there are no boys in my life." Okay, maybe there were two lurking on the fringe, circling from afar, but since I didn't know either very well, and one outright frightened me, it felt safer to close my eyes and pretend they weren't there.'"
