Description: Every other day, Kali D'Angelo blends in as a reluctant pep-rally teen at public high school—utterly human. But alternate days? She's a near-invincible hunter, stalking demons, hellhounds, and shadowy supernaturals threatening humanity, her powers surging like a "contemporary Buffy" (Publishers Weekly). Disaster looms when Kali spots a death-mark on popular classmate Jessica—doomed by otherworldly fangs. She has 24 hours to intervene... but clocks her "off" human day. Vulnerable, racing shadows, Kali must ally with enigmatic classmates, unravel cryptic lore, and weaponize wits against relentless beasts. #1 NYT bestseller Jennifer Lynn Barnes delivers action-packed YA thrills, blending indestructible hunts with high-school heart. When normalcy flips fatal, survival demands embracing the monster within—every. other. day. Recommended reading age of 14+ yrs given the mature themes explored in the book.
