I'm torn with this book. I loved the first part where they spent time together at the beach. I could have read a whole book situated right there. When it moved on to two of them going back to their usual lives, it changed a little for me. It became all tense and choppy (Sky putting up so much of a fight it seemed she didn't even like Dylan anymore, then still jumping into bed with him) and I didn't find myself enjoying being in their world.
That said, the writing is of good quality and the story moves at a decent pace. The characters are well developed and the dialogue is natural and realistic.
And one particular scene I want to point out is when Sky first stumbles onto Jem while she's trying to navigate the hallways of the mansion. I really felt the tension there and as a reader wanted to push Sky out of the room and toward safety. That scene came across as intimidating and real for me.
As a whole it's an entertaining read, and there's enough going on there that it makes me want to continue on to find out what happens to all the characters.
