Bit of a necro so sorry, but I thought you might like this blurb for the book:
“Tom, a young man of sixteen years, finds his soul kidnapped and turned into a demon to fuel a wizard’s ambition. Thrust upon him is a lifetime of servitude to his accursed master as a machine of violence. In a world that hates his kind he struggles to find meaning in his life and to deal with the essence of what is means to be evil.”
However, it doesn’t fit the cover… a blurb should always reinforce the messaging of the cover. Still, feel free to rework & use it if you like it.
