Reviewing sequels is difficult, particularly when I really liked the first one. The second was also good, but the pacing felt off in places. Now, I did read the two books pretty far apart, so take that into consideration regarding my thoughts here. The emotional trajectories of some of the character arcs (particularly Nitsos and Rhea) did not feel steady. At the end of the first book, Nitsos's position seems like it is going to be very important, but that promise is not fulfilled in the second book the way I wanted it to be. I really loved Rhea as a character in the first book, but some of her choices seemed...weird in the second one. I liked her story overall, but a few places (such as with Falka) felt a little forced and didn't seem to add much to Rhea's arc or the book as a whole. 

I loved Chrysanthi (and Andrija!). That narrative was emotional, engaging, and weirdly charming. Some of the emotional stakes did not seem as high as the author might've wanted them to be, but overall, her story and the way her story ends particularly were well-done. Some people might not like that the book is so character-focused when there is a lot of politicking and war and such going on in the background, but the focus on the four siblings stays true to the energy of the first book. This is a series about the characters and how they deal with what is happening, not about what is happening itself. 

I'd recommend the series to people who like rich people problems (and their downfall), people who prefer stories that aren't about saving the world, and people who like rooting for the anti-hero.
