When I first saw the title I believed that it was about a girl and after reading the poem I realize that it was a love story of a girl and the narrator and the girl was killed but their love never died.
The Tone in this Poem was romantic and also sad at the same time, some words that pushed these feelings were words such as "love, envying, chilling, demons,killing, and soul"
The Shift in this Poem was when ever she died things went from happy and fairy tale like to all sad and depressing.
There is no set rhyme scheme or syllable count in this poem but it is a very likable poem and I would recommend reading it to others.
The overall theme of this Poem is that true love never dies and these two kids show this.
