Daaaaaaark. Love it though. Much respect for not shying away from some very atrocious/hard themes; humanity comes in all flavors.
I Love my MC, I love that they're broken and not just magically - - fixed, despite being rescued. There's such, such Trauma there - and that mind may never be 'un-broken'. Not to mention the arms. I think that's what interests me most: Seeing how this very clearly broken child will grow up; what they will become. (You explained the 'Pain' and 'Void' cycle and its Repetition incredibly well, btw) Havard and Lexi and Ethel (I think my MC will like her most) all seem like genuinely good souls. They'll have their work cut out for them -- and it's nice seeing the frustration in wanting to help, but being unable to in their POVs; but time and them proving their words will do wonders. Very interested to see how twins interaction will go. (And if there will be romance? Because - OOF. Just: OOF.) That 'red and white stuff' highly concerned me; but I also love broken babes finding empathy in one another.
That last interlude... Of course, the 'bad people' couldn't be totally gone. Looks like there's definitely going to be -- 'something' fighting to do more Terrible things to my baby. Keeping an eye on this one~
