This was a near perfect conclusion to a brilliant series. This is probably my favourite MG series. It is imaginative and inspiring, and will definitely give young minds lots to think about. 
 Son is the long anticipated book four, and it did tie in all those loose threads from the previous three books. It brought back the favourite characters, and explained all the outcomes. It did, however, still leave me wanting more. It wasn't the nice, tidy ending I was hoping for. This series could very easily have a fifth book, with no complaints. 
 The book is broken into three parts. Part one brings us back to the community of The Giver. Although instead of hearing Jonas' perspective, we are now hearing Claire's voice. She is a "vessel", a birthmother. Only, she is where it all began. Fitting that it should end with her as well. 
 Part two follows Claire on her journey out of the community. She is enveloped into a foreign world, and I fell in absolute LOVE! with this part of the book. I would read a whole book just about that world. *Hint, hint Miss Lowry* 
 Part three reunites our favourite characters, Jonas and Kira, with Claire. I loved to see where the characters had ended up, and the new dynamic with Claire was an easy chemistry. 
 I highly recommend this series to young and old readers alike!
