The books opens with this scene:
Right from the start as a reader I had to stop and try to imagine myself in this place. I couldn't imagine being forced to survive trapped underground with no hope of escape. Also, when Eli finds out his twin brother and grandmother don't make it to the shelter and die, the setting causes even more thought. Eli's father, mother, and sisters Lexie and Terese managed to get safely inside within the forty minutes needed to survive, but his twin brother Eddie and his grandmother didn't make it..
Compound is a great book with a lot of events that bring you into the book and make you wonder what you would do in this situation. The setting controls the lives of the characters and the entire story.
