A Resonance of Power. The Resonant Arcana, #2

A city of shadows. A grimoire of secrets. And a power that could be her salvation-or her doom. After the mysterious death of her friend Selene, librarian Vesper Ainsley finds herself bound to a powerful grimoire that should never have been within her grasp. This book draws her into Nightreach-a shadow city of dangerous magic and hidden agendas, where every step reveals more secrets about Selene's fate and the forces now hunting Vesper.
Facing ruthless magical factions, Vesper is thrust into the dark world of the Luminous Concordat, a secretive council of powerful witches who challenge her to prove herself through perilous trials. Her only ally is Rafe, a brooding mage with secrets of his own, yet as Vesper's powers awaken, even he may not be able to shield her from the dangers she faces. Powerful mages vie for control of the grimoire, willing to manipulate, betray, and kill to get their hands on it.
As the trials unfold, Vesper must confront the truth of Selene's death, endure deadly rivalries, and master her own burgeoning power. But in a world where shadows move and alliances shift like quicksand, survival will demand sacrifices she may not be ready to make. For fans of dark urban fantasy and suspenseful magic, A Resonance of Power pulls readers into a world of ancient power and intrigue, where betrayal lurks in every corner and the path to truth may claim the ultimate price.
