Agnes loves living in Red Creek in the compound. She is highly religious and dutiful. Her brother suffers from Type 1 Diabetes, so Agnes has to secretly meet with outsiders to get insulin so her brother can live. She finds out there is an epidemic going around and the prophet wants them in a bunker for 400 days. She runs with her brother and learns that Red Creek is a cult and that her prophet is a liar and murderer.
This book has dual point of views from the two sisters-Agnes and Beth. There is a lot of talk of faith and God. I found some parts to be far fetched and crazed. Overall, it was a great book.
