It was an okay read, as far as BattleTech books go. The fact that it was Horses-centric, a first for the franchise, made this an insta-buy for me. But there were a few things that felt off to me. I'll spoiler-tag them for those who haven't read yet.
The biggest thing I noticed was the Horses having such a poor attitude about their lower castes when previous books, namely A Rending of Falcons, established the literal opposite of this; there, we saw warriors helping the techs do maintenance checks and competing in sporting events with techs (and losing to them!), and it was disappointing to see this forgotten about. But I've noticed that a lot of writers either didn't read some of the MWDA novels like this or just decided to ignore them, and neither of those things sit well with me in what is supposed to be a collective, collaborative shared universe.
As for Peter Cobb, the POV character of the book, he just feels like another retread in the vein of characters like James Cobb, Noritomo Helmer, Stephanie Chistu, etc., the types that want to fix whatever wrongs their leadership has done, with nothing that really made him interesting to read about. I'm sure he'll make a perfectly fine, if bland, Khan one day, but he just didn't hit the mark for me.
There were also a couple of info-dumps that felt like they were transcribed almost verbatim from the sourcebooks. I could be wrong about this, and it's not the worst thing in the world, but it was definitely something I noticed because I'm pretty familiar with those sourcebook entries.
All in all, though, it was an entertaining read. I finished it in one sitting last night.
