God of Ruin (Legacy of Gods #4) by Rina Kent:

I’m out for revenge.
After careful planning, I gave the man who messed with my family a taste of his own medicine.
I thought it’d end there.
It didn’t.
Landon King is a genius artist, a posh rich boy, and my worst nightmare.
He’s decided that I’m the new addition to his chess game.
Too bad for him, I’m no pawn.
If he hits, I hit back, twice as hard and with the same hostility.
He says he’ll ruin me.
Little does he know that ruination goes both ways.
