For readers not familiar with goodreads ratings, three stars is "I liked it".
A little less magical in this one. Not satisfied with how the battle-for-control was handled.
In book 1, we got to be in on the scheming, similar to a heist movie, but here it's like we get told stuff after it's happened. I think that's due to the technology leaps, but in a perfect version of this book those would be flushed out, etc. Can't really fault it for that.
Honestly I'm at a toss on recommending this one. I'd say go for it, since book 1 was free and terrific, I don't see why you wouldn't throw a few moneys the authors way for the next in the series.
Give this one a chance, and if you like it continue the series, and if you don't, stop at the end of this one.
