I'm somewhat surprised by the great reviews for this book. I picked it up as a Kindle freebie, intrigued by the description, but unfamiliar with the authors or plot. I found myself drawn into the book very quickly and had a hard time putting it down. I couldn't wait to see what happened next, couldn't wait for answers to the MANY questions the characters face. The characters were fairly likable, the writing and editing solid. I really enjoyed it and fully expected to be able to give a great review.
Coming to the apex of the action, the book just ends. Right in the middle of an action packed scene, no warning; it just... ends. No resolution, no answers. Nothing. Just promise of a sequel. Wait, what?? It almost feels like the authors wrote a longer novel, decided to break it into two shorter novels, and just randomly picked a spot to "pause" the story. An unfortunate, frustrating spot to stop.
I wanted to give it 2 stars, but that's not fair. I liked the story, the creative ideas, the writing. I was just so mad at the (non-) ending that I can't give it a great rating. I'm giving it the benefit of the doubt because I think the sequel will hold a lot of answers and will be just as entertaining as this was. But if you're going to release a stand-alone novel, I feel that you should at least include SOME resolution by the end. Cliffhangers are fine by me, but this is ridiculous. 2 1/2 stars (but I will probably break down and buy the sequel sooner rather than later).
