It's 2:31 in the morning but I just couldn't shut down without telling you how much I enjoyed this story. You gave the traditional "if the bad guys won" idea a fresh spin. The beginning of your story did a great job in setting the mood and explaining/teasing us with bits of the backstory. I enjoyed the Snarry parts a lot. The pace of the relationship was quite fast (almost rushed) but it just fitted very well with the war-torn, dangerous world they lived in. Honestly, who has time to dicker around and be angsty when you're trying to find your son who is in the hands of a power-crazed megalomaniac, save your god-son from being a research experiment and rescue wizard-kind along the way. With that said, I'm grateful to see more than just bam-wham-thank you mam.
The only pique I have here is the one-dimensional evil overlord. The ending scene was a bit too rushed and he died too quickly and painlessly. Just the killing curse... you were too nice. Terry had it so much worse.
Overall, this was the highlight of my evening. Thank you for your story and please keep writing! I look forward to reading more of your work.
