Valerie Valdes’s 2023 Where Peace Is Lost is a science fantasy novel. While it could serve as volume one of an ongoing series, it works as a stand-alone novel.
Facing a war whose costs would be unbearable even should her side win, Kelana Gardavros helped broker a peace with the rapacious Prixori Anocracy, also known as the Pale. Following the cessation of overt hostilities, Kel went into exile. For five years, she has lived quietly on Loth.
Loth is a backwater planet too distant and poor for the Pale to bother conquering it. This will not prevent the Pale from presenting a clear and present danger to Loth. It will not save Kel from being forced to choose between maintaining her low profile or trying to save her neighbors.
