I'll just say this right up-front: This will never be my favorite book on the shelf.
Now that I've gotten that off my chest, let's move on. This was still an enjoyable read. I'm not a huge fan of first-person narratives, for the most part, so I admit that I struggled some getting into the book. But some people adore it, so if you're one of those readers, this shouldn't be an issue for you. I don't hold that against the novel, but I thought fellow potential readers may want the heads-up.
From the first pages in, I had a sense of a larger world. I remember thinking that "I'd better get some answers soon, or I'll go nuts." N.R. Tupper did give me some of my answers, but was smart enough to leave enough open about the world and the characters that I would like to know more. Since this is a series, that is a great strength with the first novel. It stands solo fairly well - the plot arc is complete, there is some resolution for the characters - but the sequel hook is definitely there, as the characters are poised to begin a new adventure. "To Be Continued" - sure, I'll read more!
I was reading an advance copy that was loaned to me, so there were some errors that had yet to be corrected - minor bumps and none of them enough to jar me from the story. Even if they aren't all caught in the final edition, I think readers will be okay.
There are hints of where the author may have gotten some of the inspiration for this, but hey, hints are fine. N.R. Tupper gives those hints enough original flavor to keep you interested, rather than presuming it will be "same old, same old."
I will also note that it felt like as the story progressed, so did the writing. The signs of this being a first novel are there, but I can easily picture some of what felt (personally) like flow and pacing issues (Kai occasionally seems a bit repetitive in her thoughts) will disappear as the books progress.
All in all, this provided me with some sci-fi fun and kept my interest from start to finish. I can see myself reading the next book when it comes out.
