This book was chalked full of drama, suspense, romance and sadness. Callie is basically forced to do something that she does not really want to do, but, in order to make a better life for herself and her brother she decides to go for it. Callie agrees to become a renter for Prime Destinations, but when she wakes up part way through her rental cycle, she realizes that something is terribly wrong. She also starts hearing a voice in her head warning her not to return to Prime Destinations. Should she listen? 
 The writer drew the awful picture perfectly of what Callie and her family have to live through everyday. They struggle to literally survive by scavenging food, shelter and even water. Throughout most of the book, I was on the edge of my seat with worry about these characters. There were many twists and turns to the story and the reader never could even guess what was going to happen next. There was no way to predict the ending and I was left kind of shocked. 
 The character of Callie was stronger than she gave herself credit for. The story of how she lost her parents is a tragic one and she became the sole caretaker of her brother. For such a young girl, she really puts her brothers needs before her own. Tyler is very sweet and you can really tell that he looks up to his sister. He worries about her safety and is probably fearful that he will lose her too. Michael, hmm, what can I say about Michael. Michael is a sweet guy and he looks out for Callie and Tyler. They have kind of formed their own little family. I believe that Michael has feelings there for Callie, but it was not really acted on too much throughout the book. 
 Callie does have a love interest in the senator's grandson which plays a HUGE part in the book. I cannot say that I think he is the one for her though, I am rooting for Michael! 
 I really enjoyed the premise and look forward to the next book in the series, Enders, coming sometime winter 2012. I hope that the next book gives us a little more of a glimpse into the spore wars which started it all. 
 "Did Cinderella ever consider fessing up to the prince, that night she was enjoying herself in the fancy ball gown? Did she even think of telling him, oh, by the way, Prince, the coach isn't mine, I'm really a filthy little barefoot servant on borrowed time? No. She took her moment. And then went quietly away after midnight."
