 I hesitate because the first 40% was quite slow. 
 But after that it picked up, it got interesting, a little grittier. Fantastic world building. 
 And I'm kind of a sucker for alien-earthling romance. I know, I'm weird. 
 But hey, that's what you get when you combine an enthusiastic Sci-Fi lover and an excitable spirit. 
 I'm just defenseless for these things. I don't know why. I can be absolutely brutal in some of my reviews, but I very rarely read a Sci-Fi I don't like. 
 I guess it's just my sweet-spot...or weak-spot depending on how you look at it.
