From the acclaimed author of Brighter than Scale, Swifter than Flame and The Black Tides of Heaven comes an epic tale of love, betrayal, and obsession across lifetimes—because some bonds, no matter how twisted, cannot be broken.

Five hundred years ago, a young man fell in love with a prince and helped him unlock the secret of immortality. This gift was bestowed upon the few closest to the Emperor, so that each immortal was reborn again and again, their one life lived across many mortal bodies.

When the young man, Ennidar, dared to steal immortality for himself, he was forsaken by the prince who had once pledged his undying love. Ennidar was punished with imprisonment, locked away in a tower to live out not only that life but every life to come in complete isolation.

But Ennidar has not been idle in their imprisonment. They have spent ten lives plotting their escape. Now, it is time to act.

In this life, Ennidar will finally have her revenge. Against the captors who tormented her. Against the Empire that hunted her. And against the prince who betrayed her very soul all those years ago.
