The War of a Hundred Selves. The Empire of Borrowed Bodies, #4

An emperor divided against himself. A revolutionary who can become an army. A love that may not survive the return of the body that began it all. The Empire of Avarre is collapsing beneath the weight of its borrowed lives. Awakened fragments of Emperor Vaustian Rhel now inhabit citizens across the capital-and more than one has declared itself the rightful ruler. Conflicting imperial commands paralyze hospitals, courts, armies, and transfer chambers, leaving thousands trapped in bodies they cannot legally abandon.
As Saelis Dorran fights to have every fragment recognized as an independent person, Kerron Auvray is offered the answer he has pursued for years: a preserved body said to be his original form. But when Kerron enters it, Saelis no longer recognizes the man she loves. The body carries the instincts of a ruler, the memories of political prisoners, and a terrible authority over every consciousness related to it.
With each passing hour, Kerron becomes more certain of who he was-and less like the person he chose to become. Meanwhile, revolutionary leader Odrienne Vask discovers a way to be present wherever the empire causes suffering. By copying herself into willing bodies, she can rescue hundreds. Defend every refuge. Fight every tyrant. Until the copies begin to disagree. Until consent becomes an obstacle.
Until one liberator becomes a hundred competing versions of the same woman. With the first fragmentation chamber in reach of every warring faction, Saelis must decide whether identity belongs to the body, the memory, the source-or the person who survives them all. And Kerron must choose between the certainty of his origin and the uncertain love that taught him he could become someone new. The War of a Hundred Selves is the fourth book in The Empire of Borrowed Bodies, a dark romantic fantasy series about shifting identities, dangerous intimacy, bodily autonomy, imperial conspiracy, and love chosen again and again.
