Scars and Burns by M.C. Lawson

Scars and Burns is a dark fantasy romance. Dinalia and Aeron are just two kids forced to grow up and have their innocence stripped away at a young age. Both on their own journey of self-worth to prove the rest of the world they are more than what meets the eye.
Dinalia vows to never be afraid in the face of danger again. Developing her fighting and magical ability she becomes lethal to anyone who dares cross her. But even through all her skills she fails to find peace and acceptance. Obscure and out of place. Lonely and isolated in her own heart and soul. She wonders if she’ll ever escape the utter nothingness of her own mind until she locks eyes with a boy turned man whom she has yet to determine if he is the true monster that haunts this world.
Aeron disgraced from birth. Abandoned by his mother. Worthless to his father. Though the dark formidable prince is nothing shy of remarkable. He is ready to burn this world to the ground, rising as its only king. He has but one task. Kill Dinalia. He’s trained all his life countering the darkest of magic. Enduring all the tortures this world has to offer. He’s ready but all his years of training could not prepare him for the darkness he sees in her eyes and the desire he feels in his soul.

She fears the darkness that has taken root in her soul but he is ready to coax it out of her.
