I'm not sure if I vibed with the whole online relationship at first, but this book kind of grew on me.  I won't even lie... I was here for the plot twist ending and the what the hell is going on factor.  I love to be taken by surprise by a plot twist or by a character twist.  This one hit the spot in that sense.  I think the beginning was hard for me because since there was an online anonymous aspect of it, it became hard to really connect to the MMCs until later in the story.
