Yup, it was 8th-9th grade for me (7th grade was all Pern, all the time!) I admit to taking guilty pleasure rereading them now. Or at least flipping through them giggling at the good bits ^^

Oh man, I clearly remember the first time I saw Amok Time - I was maybe 8 or 9, my parents were channel-surfing and my mom was like, "ooh, I like this episode!" I remember watching and understanding exactly why she liked it ^__^
