Assigned in a lot of classrooms, parents should check it out.
Short review: A parable version of the Hunger games, without the violence, but with a thick dose of heavy-handed moralizing.
Longer review: Less a novel, more a parable. While there are some believability issues with the backdrop, it presents a setting where Lois Lowry employs considerable skill with prose to tell a tale that works for late tweens / early teens, but still rings true for older readers. There are a few disturbing ideas in the book, such as infanticide, which - while not particularly graphic- is still a disturbing thought. Even though it is 'en vogue' to assign this book to middle-schoolers these days, parents should pre-read this one, and have discussions with their kids about the morality of what goes on in the book.
