I've officially finished. While, I still have some gripes, I have gripes with all my favorite stories. The second addition of the Ronin saga is head and shoulders over the first in terms of writing. The mistakes are fewer, for sure, but the writing is also more alive and vibrant. While the first felt a little stale, contrived, and either too fast or too slow, this has the steady feel of a truly well rounded novel.
As this is just a part in the series, there's some things one might wish to see that won't happen yet, and a sense of closure can be a little hard to find. However, I truly enjoyed reading this.
That said, for personal opinions, I find Ayva annoying most of the time, and I really really like Faye. I hope to see more Faye and that good things come of her. Also, if Faye has a crush on Gray I totally ship them.
There's some issues with the prose though. Like, some conversations felt a little unnatural, like you're waiting for them to say what you think should be said, but they don't. Like, they're conveniently idiots for a time. This does get sort of fixed as it goes on, with the dialogue feeling progressively more natural as the book goes on. By the end, I definitely felt like everything that should be addressed was addressed.
Top marks. I feel like, everything that was wrong or unpolished about the first book was fixed up and improved in this second book. If you're at all interested in the story but found yourself a bit turned off by the writing, then I'd say give it another chance, because the writing is much more at the level of a published author this time around.
