In The Most Dangerous Game, Zaroff proposes that Rainsford will be allowed to leave the island alive if Rainsford can survive being hunted by Zaroff.
The figurative language is a metaphor. That is because she didn't literally burn out by one fierce moment of fire, it's a metaphor to show the strong burst of emotions that she had at that moment that made her feel as if she was burning. It could mean either that she got angry or fell in love or anything similar.
I, himself, I, us, her, I, her, I, them
Hope this helps :)
