Zealot — Colleen Vanderlinden

Fearless. Tireless. Unstoppable... Zealot.
Death's hunter and her New Guardians have been woefully incapable of ending the rise of the undead who now plague the world, their mindless, hungry ranks increasing faster than Eunomia can cut them down.
Human governments grow weary of the immortals and the dangers they bring to the world. Desperation reigns, tempers flare, and the immortals find themselves on the brink of war from all sides.
If only that was the worst of Eunomia's problems.
An evil still walks among them, one that continues to elude Eunomia and her hunters, and everything Eunomia, Molly, and the rest of the immortals have fought so hard to protect is crumbling…
…along with E's love life.
Her trust shaken, her world falling apart, E finds herself pushing away everyone who has ever mattered to her in her quest to somehow save it all. Her single-minded devotion to her Queen and the world she loves threatens to destroy the life she was beginning to create for herself.
And when an enemy is revealed, when the unthinkable happens, the world sees just how much of herself Eunomia is willing to sacrifice in order to save what she holds dear.
Because sometimes, what the world needs… is a zealot.
