Misfit by Jon Skovron Reading project by Matt bowers
The protagonist is Jael Thompson and she is a succubus demon who can summon fire as her main demonic powers and ask the elements to do what she wants.
The antagonist is a Great duke of the hell dimension a evil version of Jack Frost who changed his name to Belial.
Everything has a weakness
The theme is that no matter if you are considered good or bad by anyone else what you do and who you decide you are is what you shall be remembered as.
I would recommend this book to my friend Austin because he loves everything to do with any sort of Gods.
