In this sequel to Firebug, Ava is having a rough time. Getting rid of Venus didn't set her free - she's still Coterie.

Her new boss seems like an improvement, but who knows if he'll stay that way? The Coterie life changes people. And since Ava's currently avoiding her friends after (disastrously) turning down a date with Lock, well, everything kind of sucks. And that's not even taking into account the feelings she might have for him.

But when a mysterious illness starts to affect magical beings, it's up to Ava and her team to stop its spread . . . or else one of them might be next.
