Oh how I love a good, satisfying duology! His Mortal Demise takes everything that was good about The Last Bloodcarver, and then just takes it up a few notches. The stakes are high, the tension even higher, and the emotional turmoil is just to die for.
Whereas book 1 was only told from Nhika's POV, this sequel becomes dual POV as we finally get an insight into Ven Kochin's troubled mind, and I was SO here for it. But more than that, we get a split timeline, with Kochin's story continuing on right where book 1 left off and Nhika's story picking up 6 months later, which created just the most addictive level of tension and mystery.
Now, I think your enjoyment of this sequel completely hinges on how much you believed in the dynamic between Nhika and Kochin at the end of book 1. Their actions are often driven by their emotions, and their feelings for each other become a large part of their personal motivations here. That said, I personally don't think it's accurate to describe this story as a fantasy romance, because this is so much more than that.
The inner journeys that we go on with these characters, and specifically with Kochin here in this sequel, were tragically beautiful, and I loved how authentically Le was able to capture their messy emotions. Even though Nhika and Kochin struggle with similar issues, the way that they process, cope and try to heal is completely different, which I really appreciated seeing. Also, we get some completely new views on the heartsooth magic through Kochin's complicated relationship with his powers, which added so much depth and nuance to the world building.
It's honestly beyond impressive to me how organically Le was able to interweave the authentic character journeys with all the other aspects of this story, especially in such a limited pagecount. We get to dive deeper into the tense political conflicts that are tearing this world and these characters apart, and I loved the painfully realistic exploration of themes of war, the veteran experience, cultural identity, colonisation, discrimination, (found) family, loss, redemption, sacrifice, the clash between science and magic, and the cost of progress.
Sure, I had to just turn off my critical brain at times and suspend my disbelief for a bit, but overall I was honestly quite surprised by how well Le was able to trick me into forgetting that this was 'just' a YA story that would probably get a happy ending; the stakes really felt so dangerously high all the time! Moreover, the side characters feel way more well developed in this sequel than they did in book 1, which also really heightened my personal investment. Spending more time with Kochin's family was just an absolute joy (even if it was bittersweet at times), and I loved seeing Mimi, Andao, and Trin getting their own time to shine.
Never knew I needed a dark, steampunk YA fantasy romance inspired by Vietnam culture in my life, but here we are. This duology was one hell of a wild ride, and I definitely recommend it if you are looking for a refreshing and diverse story that strikes the perfect balance between the hurt and the heart.
