Shane and his friends survive the first major attack against the enemy, destroying the alien ships that came to harvest the children of Earth and turn them all into slaves. However, one ship escaped, and the aliens have captured Kelly. Shane will do whatever it takes to save her, but turning his back on his friends could jeopardize the whole mission.
The enemy invades Kelly's mind, turning her into a slave soldier. She'll follow their orders, even if it means murdering her friends, including her little sister and Shane. She is helpless, trapped inside her body while it performs heinous tasks under the direction of her new masters, while her sanity and desire to live fade.
Shane returns home to make a rescue attempt, only to find Kelly commanding an army of human slave soldiers, and she's determined to make him join her ranks. Will Shane save Kelly before she gets to her sister, or will she help the enemy enslave the rest of humanity?
In this book, Shane continues his role as leader of the group of American teenagers who survived the apocalyptic events of the first book which set the stage for this series. That's one element of this series that I think is one of the most unique aspects, and how it's dealt with in the series. I couldn't help but think of everything Shane, Steve, Tracy, Laura, Jules, Kelly and all the others have gone through up to this point, and there are some developments in book three that I didn't see coming. I'm interested in seeing where it will lead, which is why I like The Last Orphans series so much.
That's not to say that Shane doesn't have his moments of having to step back and look at the situation as a whole, and I think there's a bit of character growth there. I think Steve, and to a greater extent, Maurice have been the voice of reason when Shane loses sight of the important things and needs reminded of that.
This series is one that I'd recommend to anyone who likes science fiction/dystopian/apocalyptic fiction. My rating for Enslaved is 5/5 platypires.
