In Book One: Sword of the Gods, Demascus has lived hundreds of lives, and in each one served as an assassin of fate.

In Book Two: Spinner of Lies, the ghost of a previous lover haunts Demascus, accusing him of her murder.
To prove his innocence, he must find a stolen portrait containing the trapped soul of a demigod, sending him on a trail that stretches between the Demonweb, Airspur, and an island that appears on no map.
