I would advise that readers with mental illness and autism tread carefully. This book centers an autistiic character with mental illness in his family who lives in fear that he is or will become mentally ill and has tremendous self loathing around it. His central arc is around recognizing that he isn't mentally ill, he's autistic. 
 I want to think about this one for a bit before I review. Including trigger warnings for now. 
 Trigger Warnings: (view spoiler)[ Fear and hatred of mental illness and ableism around these things (both internalized and external) is a major and constant aspect of this story and a central issue for one of the MCs. Mentally ill family member is described with intense ableism. Internalized queer hatred intertwined with internalized ableism. Descriptions of family responding to queerness with both queer hatred and ableism. Autistic character with a lot of internalized ableism, who faces a lot of ableism from others. Rescue/dependency dynamic with love interest, around the MC's autism. Threat of death, threat of harm to family are a central motivation for one of the MCs. Physical violence is referenced but not described. Description of child abuse in the past. Detailed description of child abuse and harm to animals at 88%. Child neglect, which is challenged textually and directly by other characters. (hide spoiler)]
