This is a set of two identical books, only one of them is in English language, and another one is in Russian. Written by Rouzanna Baghdasaryan (Armenia), it's nicely illustrated in color by Manana Morchiladze (Georgia).
The book in Russian is named "Temnota".
... Johan is scared of the dark. His older brother Gor tells him that, if he stops crying, he will give him his toy soldiers. Inspired by this offer, Johan finds enough courage to explore the dark in his bedroom. He comforts a crying sister, faces the monsters in the cupboard - and collects his prize: the brave commander and his soldiers!
