This is the second book in the Broken Earth fantasy trilogy by Jamison. This book continues from where the first one ended seamlessly as if part of the same book.
This book follows Essun, who is [still] looking for her daughter and Nassun, the daughter, who is growing in strength and facing personal doubts. This book also follows the guardian Shaffa, who is undergoing his own transformations. Through his eyes we learn a lot more about the guardians.
Essun and How find themselves in a comm named Castrima with its own unique marvels telling of a former vast technology that is related to the obelisks. Essun is trying to come to terms with saving the world by capturing the moon as indicated by Alibaster at the end of the first book.
Through How, we learn a lot more about the stone eaters. How reveals a lot more of himself as we see him grow (?) or maybe just reveal more of himself.
The story is written well as Jamisin takes the reader through the well-developed world she has created. The series is enjoyable and compelling. I strongly recommend reading it in order.
