I read this book in 2004 or 2005, it was an assigned reading but ignited my love for dystopian societies.
I believe it started out with someone who wakes up in a pod, I think he was eventually sent to an apartment that was being monitored. Everytime he needed someone with a particular skill someone he knew from his previous society would appear at the door. There was a restricted area referred to as the RA.
I do remember the group had to overcome their preconceived notions/initial dislike of each other in order to work together to escape their essential enslavement. The main character may have gotten into trouble which is why he was placed in a pod in the first place.
