I had anticipated this book for a year now, and it did not disappoint! At first, I was slightly skeptical of the plot compared to other books. I mean, memory loss is something that either works or doesn't, and fortunately for this book it worked.
When we last left Cammie in GG4, she was running away to find answers. In Out of Sight, Out of Time, we find out that was Cammie's last memory too. But while she doesn't remember her summer, everyone else does. Her physical appearance has changed, as well as her friends and family's attitudes towards her. Cammie is no longer the boy-crazy sixteen-year-old we met in GG1. She is now an emotionally weakened amnesiac.
This book definetly has darker undertones. From the beginning, I was questioning who to trust and even Cammie's narration left a sense that you couldn't trust her. Cammie was so broken and lost, and yet on the surface her friends and family seemed to have moved on in their life. I found myself hating Bex and Zach at times (some of my favorite characters) and instead preferring Dr. Steve or Townsend. However, as the book progressed, everyone's heartbreak was revealed.
Cammie had the most character growth as she struggled with her blank memory. It was painful to see her deal with it. I wanted so badly to not question her sanity and just believe in the character I'd grown to love. I would have liked more character development in other characters, especially Liz, and some scenes concerning Mr. Solomon, who was so important in the last book. Zach was another character I missed because even though there was plenty of scenes with him and Cammie, I felt that there are many unanswered questions in their relationship.
The plot was nonstop action and included many elements and characters from past books, something that is much appreciated. As always, Carter's plot structure and timing had me constantly flipping pages in anticipation of what would happen next. And then came the ending... oh, the ending! No spoilers, but lets just say I kept reading until I finished the book at 1am.
Overall, this book is fast paced, thought provoking and a great addition to the series. Go reread the past books and then get this one soon!
