In all honesty I give Son 31/2 stars but as I thought about it I realized that the book was interesting and as any of the books from The Giver Quartet written well and always a mystery. While the first part of the book seems rather predictable, it is the rest that truly keeps you on edge and never wanting to put it down. 
 Son is broken up into 3 parts. Before the title of the first part and takes place during the same time as The Giver. I enjoyed seeing a different side then what was presented in The Giver, especially how Claire went about her life and hearing of Jonas and how Jonas left with the baby Gabe. Between focuses on Claire's life in a village that seems to be far from the community where she grew up in. With no memories she has to go through a process of understanding new things, as Jonas did. Beyond, the last part is an interesting and lovely conclusion not only to the book but to the series. Those who have read Messenger will appreciate the end of Son.
