The Ties that Bind the Soul - Old Souls, #2

The search for answers continues... Barely escaping the Mahze clan compound with their lives, Issai and Hahri sneak back into Kairash, hoping to meet Korin as planned. The last thing they expect is to run into the very teenager Issai is determined to find while the boy is trying to protect Korin's missing little girl from a group of city guardsmen. In the ensuing chaos, both the boy and girl escape them, running off in opposite directions.
They choose to pursue the girl, and Hahri ultimately manages to convince her to go with them to meet Korin. Once together, the four Old Souls delve deeper into the strange and sometimes frightening true nature of an Old Soul, discovering abilities Issai and Hahri have only glimpsed before, while also in pursuit of both the fugitive boy and Soujin, a man rumored to have become a god-like being with the power to grant true immortality after successfully consuming a thousand Old Souls.
However, they soon learn that the Shi and slavers aren't the only ones that have been hunting them, and that they may not be the only Old Souls being hunted...
