The entire series is great. Both my daughter and I read these and had fun talking about them together.
This is an excellent young adult series. However, I like to see what my kids are reading so I read many of their books too and I thoroughly enjoyed it too!
Definitely not my favorite of the series so far. I immediately disliked Erin Murphy and was disappointed in both Hunter and Sky that they didn't argue when Erin did what she did to Morgan. They are close to the situation and should have known that the strangeness wasn't Morgan's doing. It does go to show you though that once something is put into motion, it is damn near impossible to stop.
