Good and evil. Those concepts that we have been told about since childhood. Light is good. Darkness is bad. As you get older, the line between these two concepts blurs. This is how Ilya, one of the many people who lived during Ancient Rus', is faced with this truth. His carefree life turns into a long but eventful path that leads him to a meeting with Abaddon, the Lord of Darkness, who threatens that very “good” with violence. When reading about Russian folklore, we come across either fairy tales or works of the “gotcha” type, or even read humorous stories about childhood heroes. However, what if the characters in this story were presented in a much more serious way than we are used to? Read the new book “Mercy” and find out for yourself!
