The shadows have never felt darker.
When long-buried enemies resurface, the Assassin Without a Name must break the one rule he swore never to break. After years of watching from the shadows, he finally has no choice but to reveal himself to Olivia. His sister, who believes he's dead, has built a life free from the violence that claimed their parents. Now, he has no choice but to shatter that illusion and pull her back into the very nightmare he sacrificed everything to spare her from. The reunion neither sibling wanted may be the only thing that can save them both.
Meanwhile, Isadora escapes from the shadow realm, her vendetta against Mathilda burning hotter than ever. The blood witch's resurrection brings new horrors and a thirst for revenge that endangers everyone the assassin has tried to protect.
As if that wasn't enough, the Nameless Assassin's bond with the shadow dragon, Shadowgrim, grows stranger?and more dangerous?each day. The ancient dragon despises the control the Nameless Assassin has over him, but when threats appear that endanger them both, they have no choice but to strengthen their alliance and work together.
Soon, the Nameless Assassin will come to learn that some trials require more than the ultimate sacrifice.
