'We've got at least seven hours to get what we want before the sun comes up.' School is over, and Lucy has the perfect way to celebrate: tonight she's going to find Shadow, the mysterious graffiti artist whose work appears all over the city. Somewhere in the glassy darkness, he's out there, spraying colour, birds and blue sky on the night. And Lucy knows that a guy who paints like Shadow is someone she could fall for - really fall for. The last person Lucy wants to spend this night with is Ed, the guy she's managed to avoid since punching him in the nose on the most awkward date of her life. But when Ed tells Lucy he knows where to find Shadow, the two of them are suddenly on an all-night search to places where Shadow's pieces of heartbreak and escape echo off the city walls. And what Lucy can't see is the one thing that's right before her eyes.
