The Sunbearer Trials is SO good. I loved the LGBTQ+ (especially trans) representation and the world building reminded me a lot of the Percy Jackson series but with Mexican mythology, if it met The Hunger Games. The fast paced and action packed plot was amazing and after finishing, I immediately bought the second book. Aiden Thomas didn't disappoint with The Sunbearer Trials! also: SPARKLY SPACE CHICKEN (you won't get this until you read the second book, but that was my favorite part haha).
