In the post-apocalyptic world created by O'Briend, the Enclave holds the power. It's a very Hunger Games-type of world, if that reference means anything to you. Outside the walls of the Enclave, the people struggle to survive, giving up the first three babies each month to the Enclave. This is a novel that you will start and not put down until you have read the last page. The main character, Gaia, is a sympathetic character from the beginning. The scar on her face sets her apart, even in the world outside of the Enclave. She's a strong-willed character with quite the determination when it comes to her family. When her parents are arrested by the Enclave, Gaia, scorning the advice of those around her, insists upon find a way into the Enclave to rescue her parents. Her determination, quick-thinking, and (ultimately) love drive her to impossible lengths to save those she loves. The cast of characters that she meets along the way will surprise the reader. I don't want to spoil any plot points here, so I'll suffice it to say that O'Brien's debut novel is well-written, suspenseful, and moving. The world and characters that she has created will leave your mind reeling. Don't despair: the second book in a three book deal is slated to appear later this fall.
