How does Lauren Kate use imagery in Passion?

Imagery:

"But Daniel wasn't here on holiday. He wasn't here to fall in love with the beautiful copper trader's daughter. He was here to stop a reckless girl from getting so lost in the dark moments of her past that it killed her. He was here to help her undo the curse, once and for all."

"A strange, deep understanding was unfurling in her memory. Something becoming visible in the fog of her head ... This body wasn't who she really was. It was just a shell, part of a punishment. And so the body's death wasn't a tragedy at all - it was simply the end of a chapter. A beautiful, necessary release."
