Enjoyed reading this one but found it took me longer to get through it. I didn't feel connected to any of the characters and most were unlikable with moments of likability. Nico annoyed me from the start, I didn't care for any of the guys. The girls won me over in the end but I didn't like any of them.
I like the journal entries and radio transmissions throughout. 
The twist was less twisty than I would have liked but it was an enjoyable read.
