I really love her writing is the number one thing i want to say. The way she presents thoughts with her parentheses and all and just in general the way she writes 
The way she developed the characters, and i had no problem switching around in their heads , plus i really loved , again, the way she did it, how swiftly she moved through them , sometimes incredibly quickly. Love the way something new and good came out of another story ( there's a question here about whether or not that's what always happens, sometimes more obviously than others ) 
I think the personal problems of the characters were quite realistic, the intimacy scenes were incredibly real and i appreciated that a lot. We see intimacy scenes too perfect and unreal a lot and its fine but i really liked that she took a different route with this one.
An overall really nice trilogy
