Let's start by saying this: it’s basically impossible to condense the entire history of LGBTQ YA into 15 books. It’s like trying to squash all your stuff into a suitcase before going on holiday – no matter how much you skimp and scrunch, and even sit on top of your battered old wheely number to try and zip it up, you inevitably end up having to leave out some really good stuff.
The YA, coming-of-age genre has such an amazing history of exploring love stories and relationships of all kinds, and pioneering new voices and styles, that it’s totally unsurprising that it’s been a major trailblazer in bringing a whole range of LGBTQ books to the fore and changing the landscape of LGBTQ literature across all genres and ages.
