Recommended Reading for Boys and Girls Over Eleven #1
Given his lifetime assignment at the Ceremony of Twelve, Jonas becomes the receiver of memories shared by only one other in his community and discovers the terrible truth about the society in which he lives.
Kira, an orphan with a twisted leg, lives in a world where the weak are cast aside. When she is given a task that no other community member can carry out, Kira soon realizes that she is surrounded by many mysteries and secrets. No one must know of her plans to uncover the truth about her world—and to find out what exists beyond it.
