Luminosity is a crazy adventure from the first page until the last. I loved the concept of seers v. dreamcatchers. I thought that was pretty unique. Plus, I know this doesn't matter much content wise, but I loved the font on the cover. I feel like it fits perfectly with the story. 
 Bea is a seer, and because of this she is taken from her family from birth and raised in the institution, which is where all seers go to learn their craft so they can protect the city if need be. And according to seer Beatrice's visions, (that is how they address all the seers in the book. I thought it made them sound like some kind of royals, which is what I think the Keeper was going for.) they are going to need to protect someone or something because a war is coming. And it is going to be seer v. dreamcatcher. 
 Dreamcatchers sounded like awful people. They can control dreams, which sounds peaceful but in order to live they need to take the life out of humans. At least, that is what the seers are taught at the institution. I thought stephanie Thomas did an amazing job giving the background of how the institution came about, and what the seers role in society is but I would have a liked a little bit more about the dreamcatchers. And I would have liked it through Echo, because I can't trust a single thing the Keeper tells the Seers. 
 Luminosity is not just really cool action scenes. There is a cute little love story going on. Actually it is a bit of a strange love triangle. One that I didn't love all that much. There is Gabe and Echo. I loved Gabe and I didn't really know too much about Echo. Bea felt comfortable with him and drawn to him but we didn't get to know him and I didn't even really know why she felt all that drawn to him. I would have liked a little more from his end of the story so I could have felt something for him and rooted for him a bit. But as it is, I ended up loving Gabe. He is so loyal, even though he does get a bit moody. I thought he was adorable. 
 I am really interested in reading the second book because I have a feeling there are so many answers waiting for me within it. Plus, I am really hoping to find out more about Echo and the dreamcatchers. Luminosity is a supernatural, fantasy adventure. It was an adventure I enjoyed.
