Ignore the "Age Level" and "Grade Level" info in the book description. (I was almost put off thinking this was a simple young adult story.)
It's a trader / first-contact tale. It can get light on details. The main character being fantastically rich oversimplifies a lot of sticky issues. The race contact and trading without language stuff has been done before in other books pretty much identically to this. However, the key is it's woven together very well with good characters and a (very) fast pace. If you like trader tales you'll like this one. Reminds me a lot of Cherryh's books.
Like the book before it, the end is similarly abrupt. The spelling/grammar/name mix-up is there too. Only one time was it bad enough to jar me from the story though and this is on par with books of similar caliber. If you liked book 1, this is more of the same but in my opinion bigger and better than the first story. It's going to be at least a trilogy though, and likely 5 or 6 books. I went ahead and read though as this author seems to be publishing new books at a good rate.
Don't take my review as negative, the author did a great job continuing a very fun series. Basically, he took the best pieces of several excellent stories from others and wove them into a compelling single tale that keeps providing answers as well as new mysteries, growth, combat, economics, politics, the whole cabbage. The pace necessitates that many details get glossed over, but I'm ok with that in return for never having to read a boring viewpoint or slow buildup.
Looking forward to the next one in the series.
