A quick read that, I have to admit, did make me wonder how the author was going to end it... But in the end, it was just really unrealistic in my opinion. 2 stars instead of one because I liked Ethan's brother-sister relationship with adorable little Gracie. 
 (view spoiler)[How the FUCK did they just ASSUME this kid was their kid after so many years? I know he looked like the sketch of what the kid would look like now, but like... What the fuck. I'm sorry, but it's just not very realistic to me. 
 I have to say, I was expecting the ending to be that they'd take a DNA test after all (just to make Blake more chill) and drama ensued, so I knew Ethan wasn't Ethan, but the whole FBI-at-the-door thing was unexpected! (hide spoiler)]
