I really loved this book I was on the edge of my seat when the real plot kicked init was like a monster movie you hope people survive. I really liked the characters especially Kenzi and Cage they make an interesting couple romance in a crisis it didn't feel out of place or anything like that. Even with how it started with Kenzi being taken hostage then it went into a terrible situation with most of the rest of the book being about surviving and escaping. The other characters were interesting as well they were well developed I especially liked Mia and Alexei they made for interesting characters. I really liked the plot it started out as a hostage situation it then went into a fight for survival and to escape a bunch of monsters. So overall I really enjoyed this book I will be continuing the series soon.
