aka more thoughts and opinions because i have a lot of those. my opinion!!! very subjective!!!
VA: The very first chapter. Introduces Rose, Lissa and the bond pretty effectively. Quickly establishes Rose's character as a strong woman, who makes stupid teenage brain decisions sometimes but is very noble and has a strong set of morals. Watching her desperate struggle to defend Lissa from the guardians makes you root for her from the beginning, and shows how at this point in the story she lives with a strong guardian ‘they come first’ mindset, setting up her character arc. Most important: there is a cat.
Oh and Dimitri is there I guess!!! His iconic "I'm Dimitri Belikov, I will take you to the Academy" (not verbatim) line is so cool I hate him fuck him I want to be him aaaa.
Honorable mention to the Dimitri-Natalie-Rose(somewhat) Smackdown scene following the ‘you are shadow kissed Rose you died fr’ speech from Victor. I love lore drops, I love smackdowns, and I love how it makes you as a reader put on the thinking cap and question how Victor of all people knows about this super secret fifth element no one knows about.
Frostbite (I have a soft spot for this book): The climax. Do I think Christian and Rose's telepathic masterplan where he just happens to know to burn the handcuffs is pretty idiotic? Yeah. (It reminds me of this BNHA movie in the tech island where deku and all might just stare at each other while all might is taken hostage and communicate with just their eyes and idk their souls?? for about five minutes idk it was just funny to me). It doesn't matter though, since I like pretty much everything else in that handful of chapters.
(Almost) Everything that happens is a consequence of Rose’s actions. Mason dies because he loved her so much he forsakes duty to save Rose (this part is not her fault no one asked homeboy to do that???). Rose led him on (it's just mean,but she gets credit for wanting to break up with him when she realized she was never going to stop loving Dimitri TOO BAD THIS LESSON GETS FORGOTTEN LATER!!!!), and was the reason he was even there in the first place by telling the location of the Strigoi. Christian was there because Rose didn't think to tell anyone with real authority about what Mason, Eddie and Mia did and by that point was still trying to resolve the situation on her own so she wouldn't get the blame from babbling the strigoi hideout location. She decided to involve another Moroi, and got him kidnapped alongside everyone. Etc. etc. Ofc she cant really control other people’s actions, but man, the second she gave away the info about Spokane, you just knew shit was going to go wrong.
And shit goes so wrong!! It gets REAL. The Strigoi are set up as the looming threat for the whole series and the overarching main antagonists that can't really be defeated lmao (AND THEY SHOULD'VE BEEN, WE COULD'VE HAD PEAK AND WE GOT LAST SACRIFICE INSTEAD) (this issue is easily solved by reading asoiaf instead i love those books so much i hope rr martin never dies). It's Rose's turning point as a character. Her true loss of innocence. The effect this incident has on her is felt throughout the rest of the series. It also contains the scene that made me ship Rose and Christian for about 5 paragraphs.
Honorable mention to the scene at the beginning where they find that Moroi family and their famous guardian dead and Rose thinks oh damn guess I’m not getting tested today but then the other guardians start asking her questions and Rose gets to show off how she is smart and talented and competent for about five seconds before they find that message written with blood that says that the strigoi will kill every royal family.
Shadow Kiss: The final battle again, yes sue me. Strigoi were supposed to be the main antagonists for the whole series, they're cool villains. It lands very well with the setup done in Frostbite. Rose and Christian are cool, I shipped them for about 2 pages here. (These days I’m a Dragoway truther and a Romitri enjoyer but I had a VISION ok sue me) That scene where Rose runs to the guardians to warn them about the attack and she says ‘Buria’ and everyone gets into serious business mode gives me genuine chills you really feel the gravity of the situation the first time I read it I was sweating bullets its so stressing which means is really well written.
Honorable mention to the scene where Rose leaves the Academy. The whole book gives us these crumbs of Rose's character arc of questioning the system that has raised her, and how 'ok' she really is with putting Lissa's life first every time. When she leaves, she puts herself first for once. She's allowing herself to be her own person, outside of the Academy, away from the guardians and from Lissa.
Blood Promise (and this is the best scene in the whole series): The final confrontation on the bridge. Literally everything thus far was building up to this. The ultimate 'student surpasses the teacher' mixed with the emotional climax of Rose's situation in the latter half of the book. When she asks Dimitri why does he want to turn her and he just says "oh because I want you" and she just tries to kill herself because that was not the right answer, and Dimitri saves her at the last second and she stabs him and throws him in the river... oh god, oh god. I genuinely felt like this was it. It doesn't get any better than this. I can't even explain it. It's just peak.
And then it was all for nothing because Rose can't be allowed to grieve Dimitri properly and grow as a character. I came to appreciate this Dimitri storyline and the irony of him needing to DIE to start living his own life, and his scenes in Last Sacrifice are some of my favorite because you can really see the impact his time as a Strigoi had on his life. I just like to wonder sometimes how the last books would have changed if we removed Dimitri from the situation. (This issue is easily solved by opening an ao3 tab. or a google docs tab i might write it myself someday be the change you want to see in the world folks).
Honorable mention to the prologue, as it contains my favorite quote from the whole series: “If your eyes weren't open, you wouldn't know the difference between dreaming and waking.”
Spirit Bound: I have no love lost for this book. If I had to choose, I'd say Rose's final exam, the prison breakout, or I don't know, the sequence where the age law is approved, Rose calls Tatiana a sanctimonious bitch, and Dimitri's public questioning all in the span of like a chapter or two. What I can tell you is my least favorite scene, which is of course the “Love fades, mine has” BOO TOMATO TOMATO unnecessarily cruel AND a lie, two of my least favorite things.
Last Sacrifice: This book is a mixed bag for me. For the best scene, it's a tossup between Rose and Dimitri, looking at that travel guide in that library and talking about where they would like to go (the yearning there was superb, both for each other and for a different life.) and the scene where Rose kills Victor, that one was pretty good. You could feel Rose’s distress through the pages. The books had built up that breaking point of Spirit darkness for a WHILE so it was as horrifying to witness as it was satisfying. Victor as a character is so confusing to me, because I think he works fine as the first antagonist of the series, and his appearances in later books never feel like he is overstaying his welcome, but at the same time he feels like someone who could've done so much more. We know he had plans, ideals and even his own followers, so it sucks we don't get to see him work towards the goals that initially made him target Lissa back in VA. What's really interesting too is how Victor and Lissa weren't THAT different in the end, and would've agreed on a lot of politics.
