From the author of the young adult bestseller Muffin and tea. Luka is a sixteen-year-old boy who likes to slackline, hang out with his friends and tease his twin Naďa. At least that was the case until recently, when Naďa was seriously injured on a skateboard. Now she is bedridden and in no mood for her brother's stupid jokes. Luka knows that Naďa is worried. Because of an injured hand, she can no longer play the piano that meant everything to her. He would very much like to help his sister in some way, but the truth is that they have been a bit estranged lately. Especially after Luka started transitioning a few years ago. As Luka is tormented by remorse, he remembers the game he and Naďa played as children. They wrote down a list of things they would like to achieve in the next ten years. Something like a "bucket list", i.e. a more childish and goofy version of it. They added a children's curse to it - if he doesn't fulfill it, something bad will happen. But then Luka had a stupid argument with Naďa, so he changed the curse at the last minute. He wrote there that something bad would happen to Nada. They then buried the list in the garden, and Luka would not have remembered it for a long time. However, in light of recent events, he gets it into his head that Nadia's accident is his fault and decides to complete the list. With a little help from a few loyal friends, Daniel, Kit and their cute puppy Lump...
