Heralds are the most powerful of all angels, secretive and feared, created for a single purpose. Only those most courageous and worthy earn a place within the elite choir, and only by breaking ancient oaths held sacred can the honor be stripped. It's a punishment that hasn't been imposed in over two-thousand years, until a single reckless act sets off a firestorm, threatening to consume all creation. Rise Hawke never suspected she'd been marked to play a role in the deadly events unfolding in the spiritual realm. Independent and resistant to authority, she isn't thrilled when she meets Dominik, an angel with new wings, an old grudge, and a mysterious agenda he's determined to impose. Vowing to uncover the secrets kept from her, Rise soon learns that knowing what you are isn't nearly as dangerous as discovering why. Hunted by those who want to destroy her, and controlled by those who would see her fulfill her purpose, she is forced into a brutal battle set in motion long before she was ever born. It soon becomes clear that what one angel will risk to earn the title of Herald, is matched only by what another will do to keep it.

After uncovering the mystery of her creation, Rise Hawke has embraced her divine nature and called a tenuous cease-fire with her demanding angel advisor, Dominik. With her abilities flourishing at breakneck speed, she stands dedicated to a single purpose: Earn the black wings of a Herald and take her place within the elite choir. As Rise struggles to prove herself, another battle rages. Unrest in the spiritual realm has spiraled out of control, forcing the Heralds to impose new rules, ones they enforce with increasingly brutal methods. In retaliation, an embittered faction conspires to inflict grievous injury on the Black choir, striking out against its most vulnerable member. Assailed on all sides, Rise can only watch as control over her life slips away, leaving a trail of destruction in its wake. Broken friendships, shattered illusions, and a devastating betrayal she never saw coming leave her consumed with fury, questioning the very nature of the realms and her purpose within. When she’s offered a chance to reclaim her life and forge a new path free of arbitrary rules and archaic oaths, she must decide where – and with whom – her allegiance resides.
