When someone irreplaceable vanishes without warning, how far would you go to bring them home? Cadence faces a crucial decision: skip the Eidolon Festival scheduled just before her wedding, or trust Aaron's reassurance that danger won't find them. The Vampire Queen has orchestrated something far more sinister. Six Guardians, including Aaron, are seized in a calculated strike. Now Cadence must race against time to uncover Holland's scheme, rescue her loved ones, and discover whether LIGHTS—the elite alliance of Vampire Hunters and Guardians dedicated to protecting humanity from the supernatural darkness—can survive this devastating blow. Cadence Findley stands as one of the world's most formidable Vampire Hunters, wielding her expertise within LIGHTS, an exclusive coalition sworn to defend humans from the creatures that dwell in shadow and silence. With her team facing their greatest threat yet, she must confront whether her strength and determination are enough to challenge the Vampire Queen's growing power and reclaim everything that hangs in the balance.
