For Jace Bennett and Elias James monsters are no myth. In their world, no one sweet talks vampires or cuddles werewolves. The night is dark, and the unnatural creatures lurking in it dangerous. Holding back the shadow, hunters protect an oblivious population. Once filled with ideals, Jace now hunts to avenge his family. Elias, true to his incubus nature, kills to live. When fate brings the natural born enemies together, they form an unlikely alliance to save a town from blood thirsty ghosts. Sparks fly and attraction flares, but when Jace learns Elias isn't human, prejudice threatens their fragile bond. A threat from a common enemy forces them back together and Elias' unexpectedly humane actions cast Jace's black and white convictions into shadow. Shaken and facing an impossible choice, can Jace learn to redefine monster in time to save them?
