Quite a nice read actually, bringing love-at-first-sight to a whole new level. Except that, for that supposedly electrifying, swoon-worthy romantic moment when they first laid eyes on each other, well, chemistry was supposed to bring me to a full-fledge heart attack but it didn't.Oh well, maybe I was healthier, and simultaneously duller and less sentimental than I thought. Ok then, let's move along. 
 WARNING: I don't think there really IS a plot. As in, it's general framework. Not that I'm wary of. Even if there is, it's not obviously there. But who cares, the book's strength does not lie in it's plot. It lies in the execution of the story, the subtle moments between Callum and Harper as the sizzle of their romance is intensified to a full fledged forest-fire. 
 I loved the first part [where they secretly liked each other like HELLO GET A GRIP AND CONFESS ALREADY but the circumstances forced then to be together (secret grin from both sides)], abhorred it at the end [what kind of misunderstanding like that slip between you guys, like come on, after staying together for 2 years you guys can even make that kind of a mistake?!] but all in all it ended positively and on a [sweet] note. 
 So yes, this book is good, definitely a fun and even humorous read. I loved the journey.
