The book "Mother-in-law: A Novel of Our Time" by the famous American writer Gertrude Franklin Horne Atherton reveals the delicate relationship between two sisters who turn out to be each other's mothers-in-law. The author tells in detail about their showdowns, competitions and strained relationships, endowing each character with exquisite features that are characteristic of a purely American style with a feminine undertone. "In-laws" is not just a story about the clash of characters, but also a look at social norms and the conflicts that can arise in a family where power and control play an important role.
