Kyra Valorian is the most gifted Astral healer the golden-blooded realm of Aeles has seen in ages. When tragedy strikes, Kyra discovers she possesses a life-changing gift: she's a Recovrancer, able to enter the realm of the dead and recover those who've died before their time. Unfortunately, recovrancy is outlawed in her realm. Desperate for answers, Kyra will do anything to get them . . . even partner with a dangerous enemy.

Sebastian Sayre is the most sought-after Daeval assassin in all of Nocens. A silver-blooded Pyromancer, he wields fire and dreams of finding Rhannu, a legendary sword that makes its holder invincible. Since the sword was long ago stolen from Nocens and hidden where no Daeval can retrieve it, however, such a dream seems impossible . . . until he encounters the one Astral who might be both able and willing to help him.

As Kyra and Sebastian work together to uncover the secrets of their realms, they also uncover secrets within their own pasts-pasts that are far more intertwined than they ever imagined. Ultimately, in this tale of discovery, destiny, and a love strong enough to outlast time, remembering the past just may prove to be the only way to change the future.
