I've read that one, it's honestly up there as one of the worst books I've ever read. The writing is poor quality, like a high school student's creative writing assignment. There isn't a plot, nor is there any chemistry between the MC and the love interest since neither are given a single personality trait.
Beyond the writing just not being good, I sincerely don't think it should have any LGBT awards, specifically. The representation, which is apparently the only reason anyone praises the book, was honestly really terrible. The author's description of gender dysphoria included things like wanting cool hair and no zits, and nothing to do with sex characteristics.The author also seems to have some thinly veiled hatred of bisexual people, as evidenced by a few scenes in the book, implying that being bi makes you a 'gatekeeper'/bigot. The book also has passages about how everyone should be totally comfortable with being called queer (which is still used as a slur), and if they are not, then they are bad for the LGBT community and need to GTFO. I see the things presented in the book as being potentially damaging to an LGBT teenager. Especially if they are bisexual, they don't need an allegedly "diverse" and "accepting" book telling them that they are bad because they're bi. It boggles my mind that books get #cancelled because an antagonist says a no-no word, but then this thing gets an award when it states that being bisexual means you are a close-minded gatekeeper.
