After reading both Sloppy Firsts and Second Helpings, I was trying to figure out why this was on the adult shelf and not in the YA section. Well on my last trip to the library to pick up Charmed Thirds, I found out that the books are actually on both shelves. After thinking about it for quite some time I realized they could be classified as both because they follow Jessica through her high school, college and post college life so it captures all audiences. I have enjoyed following Jessica's triumphs and tribulates through high school and am looking forward to seeing what she gets in to next in Charmed Thirds.
