Coldtown is dangerous. A prison for the damned and those who party with them.

From the New York Times bestselling author of The Cruel Prince comes a deliciously dark YA novel for fans of Twilight and The Vampire Diaries. Tana lives in a world where walled cities called Coldtowns exist.

In them, quarantined monsters and humans mingle in a decadently bloody mix of predator and prey.

It's an eternal party, shown on TV 24 hours a day - gorgeous, glamorous and deadly!

The only problem is, once you pass through Coldtown's gates, you can never leave ... When Tana wakes up one morning after a perfectly ordinary party, she finds herself surrounded by corpses.

The only other survivors of the massacre are her ex-boyfriend, infected and on the edge, and a mysterious boy burdened with a terrible secret.

Shaken and determined, Tana enters a race against the clock to save the three of them the only way she knows how: by going straight to the heart of Coldtown itself. A wholly original story of rage and revenge, love and loathing from bestselling and critically acclaimed author of The Spiderwick Chronicles and The Folk of the Air series, Holly Black.
