Meh. It was engaging in places, but I found myself annoyed at the "futuristic" slang. It really detracted so much from the overall experience that I almost didn't finish it. Be warned, it is a total cliffhanger. It doesn't even end at a reasonable point. It feels like he just got tired of writing and stopped. Honestly, I probably won't even look for the next installment.
On the plus side, the characters were interesting and wel-written. Other than the annoying slang, the world building was well composed and felt well thought out.
