Marionette has been in love with Adrian ever since he handed her that umbrella, and now her love has grown, after twenty minutes alone with Adrian in a mysterious shed, she's sure that he is he one true love. She would never have guessed what would happen next, though. Also, Adrian's brother, Josh appears on the scene, who has strangely never been mentioned before by Adrian, and Marionette is determined to find out why Josh has been a secret all these years, and why he never came to school. Meanwhile, Nathanial tries to figure out how Adrian does that weird thing where he scratches his head and makes every girl fall for him, as he tries to get Marionette's attention. A great read for all Miraculous Ladybug fans! (If you are not familiar with the show, then I would advise doing some research or becoming familiar with the show before reading this book, as it contains a lot of references that will only be recognised by people that have watched it). This story is suitable for all ages.
