This is a book that gives a somewhat similar feel to the allegory of Plato's Cave. It deals with many interesting concepts and is overall a good example of a dystopian society. I found it was very good however, looking back there are some things I want to address that may (or may not) affect whether you read this book/ recommend it to someone else.
-This story is very deep and insightful, but it may present things that can be missed by younger readers.
-Speaking of youger readers, this book (although it is suitable for kids in middle school) might be harder to fully understand and may be boring for them (some things may require an explanation). The book also talks about things (and topics) like infanticide which might be unsettling to some readers.
-However, (to me) this book was overall very intriguing
Note: It is important to note that this book is part of a quartet and that some things will make more sense if you know it is part of a series.
