Broken Souls

My wife betrayed me. And now she must suffer.
 
I am the Boss of the Shadow Domain and a witch without magic. All my life, I have been betrayed by those close to me.
 
But when my lovely wife, the woman I've chosen to blood bond with so our souls are tied together for all eternity, does the same?
 
I do not just wish to kill her like I have done all the others.
 
I want to punish her.
 
I want to make her feel the pain I feel.
 
So I tie her to a chair and torture her so badly, she can never use her magic again.
 
And then I find out my lovely wife...
 
is innocent.

Miranda Grant is not a serial killer
 
As an author of fantasy and paranormal romance, she just needs to know some things, like how many dead babies can fit in a bathtub (34, 52.5 if blended), what human meat tastes like (dry pork), how to get away with murder (it's really hard to tell the difference between a drowning accident and a drowning murder, just saying), etc.
 
This non-serial killer lady lives with her partner, who often drags her outside, claiming 'sunlight is necessary' and 'social interactions are a good thing'. Given her questionable search history, she goes along with it, thinking it'll be better to have less 'aloof serial killer vibes' should the police ever knock on her door...
