MacKayla Lane haría cualquier cosa para salvar su amado hogar. Es una sidhe-seer muy poderosa y ya ha luchado y vencido al mortal Sinsar Dubh —un libro antiguo que esconde un mal terrible—, sin embargo, la fuerza con la que la domina nunca ha sido tan intensa.

Cuando en Halloween cayó el muro que protegía a los humanos de los seductores e insaciables fae, los inmortales, que tanto tiempo llevaban confinados, saquearon el planeta. Ahora Dublín está en guerra; seelie y unseelie se disputan el poder con nueve antiguos inmortales que llevan milenios gobernando la ciudad; una banda rival de sidhe-seers invade la ciudad con la intención de hacerla suya, y la antigua protegida de Mac y mejor amiga, Dani «Mega» O’Malley, se ha convertido en su peor enemiga. Mac solo puede contar con el peligroso inmortal Jericho Barrons, pero incluso su feroz vínculo deberá hacer frente a las dudas de la traición./br> En un mundo en el que mantenerse con vida es una batalla constante y cada alianza tiene un precio, Mac deberá librar una batalla épica contra las fuerzas oscuras para decidir en quién puede confiar y cuál es el precio que está dispuesta a pagar para sobrevivir.

Immortal Faerie and ancient feuds, secrets and sacrifices - a thrilling new chapter in the bestselling Fever series begins, featuring Dani, Ryodan, and other beloved characters, as they battle to save Dublin from the rising of a terrifying evil determined to enslave the human race.

There is no action without consequence.

Dani O'Malley was nine years old when the delusional, sadistic Rowena transformed her into a ruthless killer. Years later, Dani is tough and hardened, yet achingly vulnerable and fiercely compassionate, living alone by her own exacting code. Despite the scars on her body, and driven by deeper ones carved into her soul, no one is more committed to protecting Dublin. By day she ensures the safety of those she rescues, by night she hunts evil, dispensing justice swiftly and without mercy, determined to give to those she cares for the peace she has never known.

There is no power without price.

When the Faerie Queen used the dangerously powerful Song of Making to heal the world from the damage done by the Hoar Frost King, catastrophic magic seeped deep into the earth, giving rise to horrifying, unforeseen consequences - and now deadly enemies plot in the darkness, preparing to enslave the human race and unleash an ancient reign of Hell on Earth.

There is no future without sacrifice.

With the lethal, immortal Ryodan at her side, armed with the epic Sword of Light, Dani once again battles to save the world, but her past comes back to haunt her with a vengeance, demanding an unspeakable price for the power she needs to save the human race. And no one - not even Ryodan, who would move the very stars for her - can save her this time.
