This is brilliantly done so far. I love the feel of this IF, it's like a combination of Dexter and Hannibal (the tv series), which can only be a good thing because they were both awesome, yet it also has a freshness all its own. I'm smitten!
I truly hope you continue this story, cos it would be a terrible shame if it were to go unfinished. I'm really intrigued to see how you integrate romance in with the brutal/cold killer that is our MC (which, btw, I love!). I'm especially intrigued how it will work with Officer Kaufmann, seeing as it seems our interests lie very much in conflict. The seduction will likely be sublime. This relationship is what I'm most eager to check out!
And I have to mention that you have a fantastic writing voice - your style is clean and highly evocative, making the details of the story truly come alive in the reader's mind.
Although the Lightning Thief isn't really my jam (Just personal preference, I like 18+ stuff), this story and These Crimson Strings hit all the right notes with me! So good!
I hope you'll grace us with more. 😊❤
