The Night Rising by Juliana Haygert

I’ve gained the magic of a dragon… and soon, it’ll end my existence.
My abilities have grown beyond imagining, and a dragon’s fire burns inside of me. Unfortunately, that same fire is burning me alive.
The only way to save the people I love is to unite my dragon’s power with its missing half, which exists inside my evil father. If we can defeat Paimon, the world will be safe… even if I die in the process of defeating him.
Shane refuses to give up hope. He believes there’s a way to stop my fiery demise, so we can find our forever. He wants to protect me, but no one can save me from the end I know is coming.
The only way to stop this is to let everything go up in smoke.
