Number one on her list:
Lolita by Vladimir Nabokov.Read about the other titles on Lippman's list.
I began reading this at 12 because I had inferred that it was very dirty. I think I was 19 by the time I identified the dirty parts, and by then I no longer cared. My favorite novel, hands down.
About Lippman's new novel, What the Dead Know, Wendy Werris remarked on "Lippman's almost poetic style of characterization. It's branded a mystery, but the narrative and characters are so boldly drawn that it rises well above the genre."
