I'm 26 and your daughter sounds a lot like me at that age. I also had a great mother who let me ask all kinds of questions (I was too embarrassed to ask most of them so she let me write them down on notes and she would write back) about anything. Now we have a very close relationship and I can seriously ask her ANYTHING. She overshares sometimes too about her and my dad (uuugggh ). But I love it that she's my best friend.

I have no magazines suggestions for you, but rather, if your daughter is anything like me as I suspect, Seventeen is probably not a great choice for her. I remember getting that when I was younger, starting at about 13 or 14 and I don't think I read it for more than a couple of years. I just can't get into the vapid, ultra-rich lives of celebrities, and I never cared much about doing anything with my hair or makeup. The only stuff I ever found useful was how to manage acne, because at 26 I STILL have that (also, ugh). In the whole 100 page magazine I only ever remember there being one article per issue worth reading, generally about some important women's health or women's lives sort of topic that I found interesting. After that I mostly used them to cut out pictures to decorate notebooks for school.

You could always try Mental Floss, which is generally hilarious and has some really interesting tidbits. I get the magazine and sometimes read the blog and I always enjoy it.
