My current recommended read from my 12yo is "Sal and Gabi Break the Universe" by Carlos Hernandez. It's a middle grade science fiction book. The 12yo (B) is typically really good at picking out books for me to read, as they are typically quite enjoyable. However, I was taken aback by 2 comments a character made in this book. The first being when he mentioned that someone gave "feero zucks" about an event that occurred. I guess, maybe some 12yo's walk around saying/hearing that level of cursing, but it still surprised me. The second was when the same character mentioned that the 2 protagonists were "Friends with benefits?!". I'm sure both of these flew right over my daughter's head, but was still very surprised they were included in a MG level book.
Short of that, the book is enjoyable.
