Mikolay and Julia are two seven-year-old wizards. Being seven means that they both have to do a lot of reading and writing for both magical & ordinary school. As always, Julia is the top student at both schools. However, Mikolay has a problem, which he is very ashamed of and doesn't want to talk to anyone about. It is his "secret". After a lot of pleading, Julia discovers that all the letters look similar to one another for Mikolay, which makes reading & writing very difficult for him. Julia tries everything in her power to help Mikolay solve the problem. However, it turns out to be a lot more difficult than either of them thought.
