Yes, I finished this in one day. Partially because I am sick and had the time, partially because I was so enraptured by the story that I didn't set it down once. Great world building, romance that wasn't at all forced or insta-love, characters who felt real and were likable - this book had it all for me. 
 EDITED TO ADD: I THOUGHT THE SECOND ONE WAS OUT ALREADY. Super bummed.
