All of my books are a level 1-2. Mostly hand holding, mild to deeper kisses (low description), and fade to black if sex is involved. No one has sex on the page, but it is alluded to.
Book one, Someone to Catch My Teardrops contains a bus crash scene. In book two, Belonging Season, there are mild descriptions of physical violence, narcissistic abuse, drug use, mental health issues and alcohol use.
