Marjorie Asked: Trashy Novels?

Maggie says:
I'm going to blame it on all the cold medicine I've been taking, because I completely missed Marjorie's burning question yesterday in the middle of her Goodreads endorsement:

Believe me, there's been a lot of trashy potboiler reading over the years. ... So what's your all-time favorite trashy novel? Come on, tell me. I'll probably decide on what mine is by the end of the day.

Ooh, ooh, tell us!!! I could use some trashy novel-talk this morning.
