I absolutely loved the concluding part to this Trilogy. I've finished this book totally on Central Jesse Cloud Nine. 
 You must read the first 2 books before this one; it is a trilogy and cannot be read as a standalone. 
 I loved book one, got a little annoyed with book 2 (although still needed to read on), but found the conclusion and book 3 fantastic. As expected there were still some twists and turns and a few shockers, but nothing that the 'unbreakable' Jesse and Ava cannot see through! 
 Fantastic ending and brilliant Epilogue... Although I would still love to read more about Sam and Kate!!!
