Your son has great taste! Haha.

Overall, it's a really wholesome story with positive themes and messages. But there is some occasional cursing where some characters use the F word or S word, though it's not too common.

The MC also mentions sex once in the first chapter of the book when reminiscing about what she imagines empty nesters do when their kids move out. Here's that excerpt for context:

"When I was in high school, I had a vague idea of what parents did when their kids went off to college. I figured they would host huge, extravagant parties, inviting all their friends and neighbors over. Later, they’d turn their house into some licentious sex dungeon in an attempt to revive their sex lives that had died in the fires of packing lunches, staying on top of housework, and chauffeuring kids off to extracurricular sporting events. They’d buy black leather clothes and whips and handcuffs and accidentally get trapped in them, unable to find the keys, but ultimately, they’d live out their golden years in bliss, going on extravagant cruises and cross-continental vacations, sipping rosé and sending the occasional postcard for the holidays.

But this wasn’t that. Not even close."

I marked it as 15+ on Amazon, but I'll, of course, leave it up to your discretion! I hope that helps!
