The Sugared Game by KJ Charles: Book 2 of the Will Darling Adventures was maybe even better than book 1 (though definitely read book 1, Slippery Creatures, first—it's really good and you need it to understand this second installment). Lots more relationship growth, lots more insight into why Kim is the way he is, and a fast-paced, suspenseful story. Also, Maisie and Phoebe are wonderful. I'm looking forward to the third book.
Boyfriend Material by Alexis Hall: Luc and Oliver agree to be fake boyfriends even though they don't much like each other at the beginning—some great tropes right there. This book is fun and funny (I laughed so much!) and lovely. It deals with some serious topics too, and there are some deep feelings and wonderful chemistry between the main characters.
Cemetery Boys by Aiden Thomas: A trans boy is determined to prove he's a brujo to his traditional Latinx family, so he summons a ghost...and ends up falling in love with him. This was seriously delightful. There are some heavy things here, but oh my gosh, it was lovely and left me smiling so much. And since I listened to it while packing and hauling boxes around, that it got me smiling so much was really something! The narration is also excellent.
What did you read and love in September?
