Read Petronius' The Satyricon (12). That dude was messed up.
In no particular order (certainly not in the order that I've read them):
Too Much Temptation by Lori Foster (13)
The Princess Diaries (14) (vetting it for Kayla, nominally; it's too old for her yet, both in themes and language)
The Fellowship of the Ring by Tolkein (15)
....
Is that possibly all I've really read? Feels like so much more. Hm. Disturbing...
Of course, if you factor in the parts of books and the journal articles I've read in the last two months, it would probably equal another three books. I know all there is to find out in the media about conjoined twins; I know a fair amount about language revival amongst Native Americans (though certainly not all there is to know).
Hm.
