Children of Jubilee by Margaret Peterson Haddix
Since the Enforcers raided Refuge City, Rosi, Edwy, and the others are captured and forced to work as slave labor on an alien planet, digging up strange pearls. Weak and hungry, none of them are certain they will make it out of this alive.
But Edwy’s tech-savvy sister, Kiandra, has always been the one with all the answers, and so they turn to her. But Kiandra realizes that she can’t find her way out of this one on her own, and they all might need to rely on young Cana and her alien friend if they are going to survive.
When trying to prove the cruelty of the Enforcers, the children are captured and taken to an off-world prison. Each are forced to work in a mine in a seemingly hopeless situation. Until one little girl makes a strange friend.
Children of Jubilee is the third and final installment in this post-apocalyptic scifi series for middle readers. Rosi and Edwy and the rest of the kids that escaped are all together again. But their adventures have just begun. This final chapter is the most suspenseful and exciting yet. It was extremely hard to put down. And I loved the climactic ending with plenty of surprises along the way. I only wish this series would continue past the first 3 novels. These are great characters and a fun, unique setting. I definitely recommend this well-written and engaging series.
