Demon's Alliance. The Demon's Series, #3

Who wants a demon for an ally? Throughout recorded history, the Anesh Archipelago has been plagued by demons: beings of pure evil, without conscience, irredeemable. That was the unquestioned truth - until the angels granted a demon hunter's sigil to a demon: Bright. But when Guild White accepted Bright as a hunter-in-training, that didn't settle the question. Instead, it opens a rift that sets hunter against hunter.
At the center of the conflict is not just Bright, but those closest to it. Sunrise, who never wanted to be a hunter but has come to appreciate the demon she tamed. Raven, the seeker who identified Bright's sigil and whom some blame for its acceptance at Guild White. And Mercy, Raven's teammate, who has to choose between turning her back on her friends, or on everything she's been taught about demons. The division leads to violence, spreading far beyond the halls of Guild White, threatening to destroy the guild system itself.
That outcome would benefit no one: not Bright, nor its allies, nor the demon hunters who oppose it- -no one, that is, except for every other demon in Anesh.
