First thought: Wow. This is how authors should finish all of their series, the standard has been set. The new characters are beautifully flawed and the connection that they share is visceral; it is especially pleasing to see the other couples as well and the amazing chemistry that they all share. There was a slower portion towards the middle of the book but the beautiful story arc and the twists and turns of the plot definitely made up for it. A fabulous conclusion to a wonderful series, my only qualm being that I now have to let these characters go.
