Leon Hertz is 13 and 3/4 and the third Leon in his class – so he thinks he’s pretty normal and unremarkable. But Rouven has noticed him. He even helps Leon with his presentation in Ethics. When it comes to death and mourning, the boy who always wears black is certainly an expert. Leon's topic is quite heavy: he wants to talk about the accident cross of Lukas, who was hit by a truck while riding his bike a few years ago. Not only is the presentation keeping Leon awake at night, but his mood swings are also troubling him. And could it be that Rouven likes him in some way, considering how much time he spends with him? A wonderfully light novel about the difficult questions of life that not only teenagers ponder. Leon Hertz is the third Leon in his class, making him a completely unremarkable average kid. That’s what Leon thinks. But Rouven has noticed him and even helps him with his presentation in Ethics about death and mourning. Leon is relieved to get support because he hasn’t chosen the easiest topic: he wants to talk about the accident cross of Lukas, a young cyclist who was hit and fatally injured by a truck at that spot a few years ago. But it’s not just the presentation that keeps Leon awake at night; his mood swings are also weighing heavily on him. Is this still normal, or is he already feeling a bit depressed? And why is Rouven so eager to spend time with him? Does he have a crush on him?.
