The evolution and diversification of Young Adult literature (YA) in the last two decades have brought about significant changes, particularly in the representation of LGBT characters. Tropes have always been a staple in literature, but their use in YA has taken on a unique significance when it comes to LGBT representation. These tropes have developed in parallel with the political landscape of the USA and the rise of LGBT rights. In this context, the analysis of three popular YA series, Percy Jackson and The Olympians, The Mortal Instruments, and The Raven Cycle, and their respective sequels and spin-offs, becomes crucial. By examining the use of tropes and the treatment of LGBT characters in these series, we can better understand the changes that have occurred over time and the commonalities and differences among them. Moreover, this analysis will also shed light on aspects outside the novels that have contributed to these developments. While similar patterns emerge in all three series, each one handles LGBT topics differently, depending on the time of publication. Finally, we will also explore the current state of publishing and the role that communities play in shaping these popular series. By examining these issues, we can gain a better understanding of the role that literature plays in shaping our perceptions of LGBT individuals and the broader social context in which these works are produced.
