Quicksilver by Dannika Dark

In the world of crime fighting, Raven has learned that formal affairs are a necessary evil. So when Keystone receives an invitation to a winter ball, she tries to make the best of it. The most powerful elites in Cognito are attending—a perfect opportunity to network and have a few drinks. But when a guest hijacks the party in a violent display of dark power, chaos ensues.

It’s a race against time as Raven searches for a way to thwart his diabolical plan. Will Keystone find the fortitude to prevent the downfall of civilization? Or will they bow to a new king to save their souls?

“And a terrible curse befell the winter ball.”
