The main area of interest covers novels from the turn of the 20th and 21st centuries. The description of the characteristic development lines of this genre is the background for the analysis of novel Fanfik by Natalia Osińska from 2016. This novel is written using affective poetics toolbox. As a result the model of affective literature, specific reading practices and performative function of young adult is obtained. The authors of analyzed novel start from their own affects, experiences and observations and reach to the subject, teenage audiences, enabling not only a better understanding of the world and other people, but also they convey various, culturally supported, though not easy to implement decision models. The world presented in the novel is not always a friendly one and often controversial. Characters’ behaviour is not obvious but a thought-provoking axiological proposition.
