This was a nice enjoyable read and I'll definitely be continuing on to the next book. The world building was done well and the universe itself was interesting. My biggest problem, and why it only scored 3 stars, is the main characters are a little forgettable. In the moment, I was involved with the story and cared about the events happening. After I put the book down? Well, there was nothing I could point to that made either Quinn or Sara spectacular or brilliant. In fact, Donovan, Rafferty and Erik were more memorable and exactly the reason I'm looking forward to continuing.
