Lore by Alexandra Bracken

Every seven years is the Agon, when nine Greek gods walk the earth as mortals, hunted by the bloodlines of Greek heroes battling to absorb their power. After the gruesome death of her family, Lore quit the Agon, wanting nothing to do with the gods’ punishment—until an injured Athena offers her an opportunity to avenge her family. Bracken’s novel drops ancient Greek mythology into the center of modern-day Manhattan in a relentless hunt-or-be-hunted thrill-ride. The plot twists and turns at a breakneck pace, but the driving force of this high-octane urban fantasy is it’s tough, uncompromising main character. Jaded by her past and tormented by her grief, Lore must learn that sometimes vulnerability is a strength, not a weakness.
