Son

"They called her Water Claire."

When the young girl washed up on their shore, no one knew she had been a Vessel. That she had carried a Product. That it had been carved from her belly. Stolen.
Claire had had a son. She was supposed to forget him, but that was impossible. When he was taken from their community, she knew she had to follow. And so her journey began.
But here in this wind-battered village Claire is welcomed as one of their own. In the security of her new home, she is free and loved. She grows stronger. As tempted as she is by the warmth of more human kindness than she has ever known, she cannot stay. Her son is out there; a young boy by now. Claire will stop at nothing to find her child . . . even if it means trading her own life.
With Son, the two-time Newbery Medal--winning Lois Lowry has spun another mesmerizing tale in this thrilling and long-awaited conclusion to The Giver.

"Claire's story stands on its own, but as the final volume in this iconic quartet, it holistically reunites characters, reprises provocative socio-political themes, and offers a transcending message of tolerance and hope."--Kirkus Reviews, starred review
