How to Stop Time meets Thieves' Gambit and in this thrilling, romantic and witty supernatural YA novel.

Gracie was born into a secret community hidden within ordinary society: the Everlasting. Her family are abnormally long-lived, resilient and fast-healing. But, it turns out, Gracie is mortal... which means she's vulnerable.

When the truth emerges, her immortal boyfriend Arty dumps her. Even worse, while her invincible peers embrace pulse-pounding extreme sports, Gracie's parents prepare to wrap her in cotton wool. Permitted 'one last adventure', Gracie heads on an international trip with friends - though her hard-to-read ex, Arty, ends up joining them. And, as they reach New York, things take a dark turn...

Arty, an expert at parkour with the uncanny ability to bounce back from even the worst falls, has been posting stunts online, scaling the world's tallest buildings. Now a gang is blackmailing him to use his skills to pull off a dangerous heist. Now both his life and the secret of the Everlasting community is under threat... Could Gracie, a mortal girl, be the key to saving them? And could she and Arty have a future after all?
