3.5! This book started off very mediocre and I wasn't to invested in the world but the ending really picked everything up and all the things started happening at once which I liked, it just took so long to get to the action.A 
 Nemesis was created and raised to believe she wasn't human, at a young age she was engineered and trained as a killer to be purchased by a royal family for their daughter and heir. 
 Donia treats Nemesis well and tries to get her to care about more than protecting/killing anyone that threatens herself. Nemesis's training/conditioning was to well done and she doesn't think about her own well bing or feelings, only her job to protect. When Donia is called to the Galactic court under the pretence of punishment for her fathers actions Nemesis under goes a transformation to take on her identity, ready to battle court life to keep Donia safe at home. 
 The world building was lacking for me, I loved the concept, the future setting and how the royals were set up but I wanted more and felt it could have been really amazing if I just had some more descriptions or ships and planets (view spoiler)[ I did love when they went planet side, the lightning scene was hilarious but it was the first time I realised all the previous weather was engineered (hide spoiler)] but again I'm a big sci-fi fac and love description of tech that others usually find tedious xD.A 
 Nemesis is a great character and I loved her growth, in the beginningA she's very detachedA (as you would be too if you thought you were only a creature engineered to kill) which made me detached as well. I didn't feel stressed about her actions because she didn't there was no real personality at the beginning because she was so brainwashed. It's not until the second half that everything started happening and I really couldn't put the book down: Plans, over throwing royalty, assassination attempts, murder, ALL THE THINGS I WANTED! (view spoiler)[Man when Nemesis killed Elentra by REACHING in and grabbing her heart out of her chest yaaassss! (hide spoiler)] 
 Nemesis has a lot of internal struggle trying to come to facts with herself and change the beliefs she's held all her life. Her character growth is slow but towards the end of the book I loved her strength and choices. I can't wait for the next book and to see how the events start to unfold. 
 Thank you so much to Simon & Schuster for allowing me a free copy in exchange for an honest review A
