Wow, I feel like a minority here, judging by the other reviews.
Look, I wanted to like this book. I REALLY did. But here's what's keeping me from giving it a higher rating:
-parts of this story were rushed, like the story was in a hurry to tell itself just to get to the parts the author wanted to explore.
-characters were...one-note. They own their note well, but they don't have multiple facets.
-and WHY, oh WHY, does Daniel (the MC) keep getting rewarded? The only consequences he ever suffers are, "oh no, my SAI girlfriend left me AGAIN!" Even at the very end, with the LUCA reveal, he's still praised.
I give it 3 stars because the premise is intriguing, and the science IS cool. But man, the characters could have been worked on some more.
