Aw... That was a sweet ending :3
The rest was very well written; nice job!

Thank you for letting some of the truth be known. I am a religious Jewish girl and these stories are some I have grown up with. You have made me really happy to see and read that people do recognize what happens especially to the children (for Jews the child's death count was 1.5 million) and not only for the Jews the truth of what happened in concentration camps. Thank you like letting me feel that family stories and holocaust truth has not died out an the people are remembering.

Thank You

Incredible. I enjoyed every minute, which, upon reflection, was probably not a good thing. Still, those two girls growing to be healthy and happy was so unexpected, yet so sweet. You really did your research on this, and it shows

If the subject is alive during being cut open like that, it's actually referred to as 'vivisection'.

The More You Know.

Why, hello there! I've been scrawling this down on my iPhone, so I hope you don't decide to deem me as a bad writer or anything for any horrifyingly long run-on sentences.

First off, I'm just gonna say that this had my heart beating fast for the whole story. Especially the imagery with the dissection parts, so kudos on that! I could almost feel my chest cavity being slit open, and that's a compliment of your writing style :)

Anywho, this caught my eye because in the last few months I started writing a Hetalia Holocaust story set in the very same subcamp of Auschwitz. I suppose it's a PruHun by definition, although the romance is quickly toned down in favor of more important aspects and Germany, Austria, Poland, Russia, and America do play rather substantial parts as well. I mentioned Mengele (and several other notorious NSDAP members) a few odd times in it, and I actually had a reviewer say that they had read a similar fiction involving him with human experimentation a few months back. I guess I found it huh? Although in my story's case, it's our loveable little Germanic countries who start off as the SS.

I also would like to mention that really enjoy how you portrayed Russia in this although he wasn't a main character. He's interesting in fanfiction because writers interpret him in so many ways. Unfortunately, usually writers just make him a psychotic sadist and then slowly forget about this over time and he becomes bland. But here, you seem to understand by having him doing the rescuing and the surgery that he actually knows what he's doing. And thank you for not having France and England or America and Russia squabble during this fic when there are so many more important things going on. The kinship between them was a welcome change in the face of the enemy of dehuminization. I also have a bit of (non-romantic) kinship between Russia and America in my story, so it's good to know I'm not alone; although you were first by about three years xD

Anywho, you should be proud to have made such a chillingly accurate contribution to the historical hetalia field. Shame that the 'good Doctor' chickened out and ran away to South America and died there thirty years later instead of facing up to what he'd done at Nuremberg. I did a lot of research on the holocaust myself and I can really appreciate the effort you put in to this! I hope you have a nice day!

Simply amazing. I can't imagine a better story than this you are an amazing author. :)

This deserves a review I mean, c'mon 700 faves and 200 reviews? Where are the voices of readers these days! Honestly, their time in the lab made me feel... Weird? I don't understand either but you definitely gave me a good review on history since it's only next school year that I'm gonna be learning world history! Great job and keep up the good work!

Brilliant story!

This was such a good story. It was incredibly sad, but at least there was a happy ending. You did a really great job.

Ivan is a boss! Saving everyone's asses. Afred's a good big brother. _
This story is beyond amazing! I just couldn't bring myself to bookmark the page a go to bed; I was up til the sun rose trying to finish, and then went to work.
I love the time split. It connects the events perfectly, in my opinion. Well done!

Holy shit that was amazing!

So was this inspired by true facts? Was there actually dome doctor who did bat shit crazy experiments on twins? That's. disgusting. Anyways, I couldn't stop reading. The story line was gripping and memorable. I do think that it was little short on a developed plot though. But an overall good job! Keep up the wonderful writing! :)

I read allot of Holocaust fanfics, from all different fandoms, because I find them interesting and this is by far the best one I have read. To think I only came across it by accident, but I'm glad I did. You also did well to make it some what historically correct in which I congratulate you on because most seem to find it hard or stray off the historical path.

Oh wow, that was just ... Beautiful in the end of course, but the rest of it, god, so creepy and dark and... Wow. What a wonderful way to step back into hetalia.

I want to congratulate you on a fantastically executed piece. You drew me in from the first lines, making me feel for the characters as they struggled through unmentionable horrors. You handled it just right and did not go over the top or understate Dr. Mengele's experiments. Overall fantastic job and hope to see more from you!
