Walking Shadow & Whispers in Flame (LokixReader)

(This is my first book so I really hope you like it)
You are the adopted daughter of Tony (aka IronMan) and Pepper Stark, best friends with Natasha Romanoff, and had a big crush on Peter Parker, you lived a normal life accept for having fire powers that had to do with the marks on your back, they would glow a bright orange yellow whenever your mad, flustered, angry but sometimes randomly at times, but so far you've been clam as a candle by going in the library (as the only person that does go in) to sit down with your favorite book and some tea uuuunntil you told Peter you liked him but he rejected and that he already ask MJ to be his girlfriend, you got upset and run out of Stark Tower in tears to clean your mind you were running into down town city when you get hit by a shock wave, you hit the ground and before you black out you saw a man walk up to you, you only saw that he had black short hair until you faded into darkness.
