There is a lot I didn't like about this book so I will try to sort it out.

Things I didn't like -
-There was too much action. Much more than I like.

-It was really complicated and therefore I did not know what was going on a lot of the time (I cannot say that's the book's fault because it is actually my fault I started with the sixth book and not the first book)

-At one point, Dana, Emma and the rest were completely left out.

-The whole book was overly drastic!

-And Daniel had too many powers (sorry).

Things I liked -
-The things that made sense (which is mostly nothing so I'm not going to try and list them here)

-Daniel defeated (?) Number 1 in the end.

Yes, that is pretty much all I liked about this book.
Lights Out was a big disappointment and if I ever re-read it I will read the series IN ORDER!!
I can't say I would not recommend it either because technically I haven't even read the entire series yet. Like not even the first book.
