Blood of the Watcher — D.K. Holmberg

Trapped by Venass. Tormented by the Forgotten. And both desire the very ability that allowed his escape. Chased through the city by someone able to influence his Sliding, Rsiran and his friends prepare for the next attack, uncertain whether the Forgotten or Venass will move first. When Rsiran learns that his sister was abducted, he must decide whether to help a family that abandoned him. If he does not, Alyse might suffer a fate worse than any torment he has already endured. Finding answers leads him to discover a secret about his family, and himself, that changes everything that he believes, making him question who - and what - to support.
