Although it was off-putting that Nemesis had virtually no feelings, it made for a new, fresh, bittersweet YA heroine. 
 Nemesis is a Diabolic, which are engineered to look like human beings, talk like human beings, and reason like human beings, but are near indestructible and have extreme strength, speed, and technique. She feels no emotions. She struggles with it. 
 All she feels is the obligatory love for Sidonia, her master, whose parents bought the Diabolic for the sake of a new trend. But when the Emperor demands the end to all Diabolics, Sidonia, who loves Nemesis in return, refuses to kill her, and her father, traitor by heresy, agrees. Sidonia's mother, the Matriarch, loathes her husband for damning their family by working with the Excess. 
 Now, as soon as the Emperor finds out, he summons Sidonia to the heart of his court. Of course, Nemesis's unwavering love and protectiveness doesn't allow her to let Sidonia go, but Sidonia's mother, the Matriarch has a plan: Nemesis is going to disguise herself. 
 Did I mention that this is the coolest setting ever? Did I? Because it's the coolest setting ever. It's set in space ships, which mentions of six suns and burning stars and planetary living? Because it's the goddamn most amazing setting ever. + beauty bots + false-youth + IT WAS JUST SO COOL = wordscannotdescribeit. (I'm getting repetitive, aren't I?) 
 S.J Kincaid crafted her world down to every detail, and I loved it. She made it so that every conversation was a web of lies, every seemingly kind offer was dangerous, and even the most expected things unraveled to surprises you couldn't predict even if you were a Seer at the top of the Prophetic Tower in Leigh Bardugo's Language of Thorns (which is the book I just read today, forgive me for references you probably won't understand). 
 Can I even describe the mysterious, dark, complex web of lies? The betrayals and heart-wrenching scenes? Let me answer that for you. No, I can't even begin. 
 Well, to find out the rest, you'll just have to read it yourself, and if you're a fan of fantastic world-building, trillion-dimension characters. PLUS, a heart-breaking LGBT romance on you never guessed would happen. Can I ask for anything more in a dystopian/sci-fi genre?
