Statutory rape. Sex with a minor. No. Just no.
All the author had to do was make the protagonist 5 years older and I would have liked this book. But I was so close to giving up on it so many times because it was too uncomfortable to listen to a 13 yr old character describing sex and other intimate scenes with a grown man (24!). Ugh. I cannot recommend this book. The book editor failed. The publisher failed. Someone needed to make the girl older.
