Newly-appointed Prime Mancella is desperate to keep the peace within her realm and within herself. Having recently acquired the power to physically split into separate versions of herself, her identity is beginning to fracture—along with her land, which is on the brink of war. The only semblance of normalcy in her life is her budding romance with thief-turned-confidant, Silver. . . at least until the mysterious Prime Reltas arrives at her doorstep asking, or rather demanding, her hand in marriage.

If Mance wants to avoid a fight that will devastate her realm, she’ll have to consider the proposal. Even if it destroys Silver. But Mance isn't ready to give up just yet. Desperate to free herself from the betrothal, Mance must seek allyship from other Primes and learn to control her new magic. If she fails, her decision to refuse Reltas's proposal will implode the delicate state of affairs across the realms, setting off a catastrophic war—and shatter two hearts in the process.
