It kinda weirds me out (makes me feel unsettled?) that the author made use of WWII and had Lucifer's betrayal happen at that time (also, almost 100 years? when it's only been 74? but okay that's probably not a big issue).
Not to mention, the title is "Pandora's Bride"? (you mean to say that Lucifer = Pandora?) As in Pandora, the first human woman who opened the box which released the ills of humanity into the world...
I'm usually not the type to criticize (I try to always say nice things), but somehow I felt like letting that out. Still reading though to see how this goes. ✌️
