21. Witchmark by CL Polk: m/m murder mystery/fantasy. This book has an interesting investigation, which is directly linked to the fantasy worldbuilding.
22. Micah Grey by Laura Lam: fantasy of manners with a bisexual, intersex protagonist. Intersex representation is very rare and this series does a great job with it, while depicting life in a circus.
23. The Gardener's Hand by Felicia Davin: f/f/m heroic fantasy. With polyamory and telepathy, this series was made for me. The worldbuilding is great too, as it is set on a tidally-locked planet.
24. The Root by Na'amen Gobert Tilahun: portal fantasy with some m/m. This book starts with two different stories, one set in our world, the other set in a secondary world, until its diverse characters travel through the portal in Book 2.
25. The Uncrossing by Melissa Eastlake: m/m urban fantasy (YA). This book is a page-turner. Loosely inspired by Rapunzel, it creates a very original story, like a modern fairy tale.
26. The Wicker King by K. Ancrum: m/m fantastic (YA). Is it real or is it all in his head? This book is very intense. It's also a mixed-media story, with photos, drawings, playlists...
27. Ardulum by JS Fields: f/f science fiction. Here's another series with telepathy, one of my favourite tropes. There are many alien species, some close to humans, others very different.
28. The Amberlough Dossier by Lara Elena Donnelly: m/m spy thriller. I don't know much about spy stories, but these books set in an invented world are fascinating.
29. Red, White & Royal Blue by Casey McQuiston: m/m romcom. I'm not a big reader of romcoms either, but this book is a page-turner. Its protagonists are the First Son of the United States and the British Prince.
30. Jane, Unlimited by Kristin Cashore: f/f theft mystery/spy thriller/horror/parallel universe sci-fi/portal fantasy (YA). This multi-genre story is loosely based on "choose your own adventure" books. Little by little, all the pieces start to fit together.
