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 Perpetuals. 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 Perpetual 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? An original, romantic and high-stakes speculative novel from the author of Totally Deceased and Cloud Nine, perfect for fans of Jennifer Lynn Barnes. A secretive family of immortals hidden within the real world, like the Cullens in Twilight - plus a second-chance romance, the thrills of a life-threatening blackmail and heist plot, and international adventure across London, Paris, Norway and New York. Themes of time, mortality and love handled with Sue H. Cunningham's unique blend of action, humour and poignancy.
