Evil has a scent: lemon.

It was supposed to be a routine drug bust. Arrest some magic jerks and move on, but then a fellow operative is murdered, and Aviva is thrust into a perilous black ops mission to disprove corruption charges.

Meanwhile, her half-sister is being blackmailed for being an infernal, and as Avi struggles to protect her, she's set on a collision course with the one person she hoped to never meet.

And just when she thought things couldn't get any crazier, her ex drops a bomb about second chances.

Aviva must navigate a minefield of love, betrayal, and powerful Maccabees gunning for her, to expose her enemies—and keep her secrets hidden. But hey, running for your life is good cardio, right?
