Pretty sure I first read this book as a freshman in high school-- I was wandering through the library one day, it caught my eye, and I sat down to read it. I've re-read it a couple of times since then.
This book was great for me to read as a teen for many reasons (although this was one I never checked out to take home--my mother would have had a heart attack right there and then): 1) Because she talks a bit, but not a lot, about birth control and fertility drugs, I did some research about them; 2) Since I was reading a memoir from an adult perspective, it helped me get that there were points of view other than that of a 14-year-old out there, even if I disagreed with them; and 3) It opened up the world of non-YA, non-fiction literature to me, much more so than anything I'd read at school to that point did.
But of course, I didn't know any of those things then. It's only with 20+ years of hindsight that I realize how great it was that I ran across this book one day.
