At-a-glance: Light science fiction with light political intrigue and amazing main characters I can root for ~ (view spoiler)[Of course I love Tyrus (hide spoiler)]. 
 Real thoughts 
 This nearly made it to a 5-star read but (view spoiler)[the last 10% pissed me off... I know Nemesis is still learning about feelings and relationships, but I'm sure the whole audience could see that "Tyrus-killed-Sidonia" was a ploy by Grandmama Domitrian so it was honestly just so frustrating that Nemesis had so little trust in Tyrus and I felt so heartbroken for him as she was acting like a pooper =I 
 Admittedly, the author could still totally do a 180 and make it a "Tyrus-really-did-kill-Sidonia" 
 situation in the sequels but it would destroy my view of this novel and I would be way too pissed if that happened >=O !!! (hide spoiler)]. 
 My other issue would be that Nemesis feels more like a bystander goofing around and acting rashly quite a fair bit of the time. (I did enjoy her as an FMC with badass fighting skills, but... as novel that was originally planned as a standalone, she could have utilised her brains a bit more towards the end of the novel, yakno?) 
 (view spoiler)[Tyrus (hide spoiler)] seems more like the hero of the novel - the plot seems to primarily revolve around him out-maneuvering his opponents and the events that unravel leading up to (view spoiler)[his coronation. (hide spoiler)] 
 (view spoiler)[Additionally, as soon as Sidonia re-appeared from the dead... I knew she was going to die again because she had no place in the future Empire =/ just sort of felt MEH about it. Rather than being an actual character, she was sort of... a stepping stone for Nemesis' character... 
 Reasons Sidonia was left alive after supposed-death: 
 1. Give advice to Nemesis after she chucks a fit post-spooning with Tyrus/Deadly's death. 
 2. Allow Nemesis to chuck that fit so that we can add in more romantic angst =^] 
 3. To die for reals and give Nemesis an excuse to act stoopid at the end (and add in more romantic angst). (hide spoiler)] 
 I'm mildly interested in seeing where Kincaid goes with the sequels and I think I'll be super happy (view spoiler)[as long as she doesn't butcher Nemesis and Tyrus' relationship! (hide spoiler)]
