Definitely for older teens, but it offers some really good, realistic, sex advice for LGBTQ teens. The mystery side of it, with the increasingly abusive and jealous love notes Jack gets, started out strong but ended...I guess I didn't really see it coming!

Spoiler

I do feel that the pacing started out great with Jack's mood slowly depleting as the notes got worse and worse, but then suddenly, within one chapter, he's completely worn down and given up and automatically starts to think like an abused boyfriend? I felt that could have been better built up. Jack is tough, it would take him more than one chapter to completely throw in the towel. It did shock me and make me sad for that whole chapter though when he completely gave up and gave in.
