To make matters worse, her boyfriend Dmitri's demon bite is getting worse, weakening him and putting a major strain on their relationship.

Luna discovers the murders are linked to the Wendigo, shapeshifting cousins of werewolves made of smoke and shadow who drink the blood of their victims for strength. She doesn't know whether Wendigo leader Lucas Kennuka is friend or foe, but he's clearly determined to wrest her heart from Dmitiri. And if Luna doesn't discover who's behind the killings, it could destroy her fragile relationship - and cost Luna her life.
