The Dairi Burger has a hilarious recap of a Sweet Valley High book I don't even remember called "Love Letters for Sale."
Unbelievably, it's about ... love letters for sale. The twins start a business where teens hire them to WRITE LETTERS for them. As the site points out, this has never exactly been a giant teen concern, even pre-Internet. And ... well, it just gets dumber from there.
Excerpt: "They put up ads all over town (ah, these pre-internet stories are so quaint) and they get several letters the first day they check the PO box. They go through some of the requests where people write to them explaining the background info about why they want to send a letter, and what they want the letter to say.
OMG ARE YOU KIDDING ME? IF YOU TOOK THE TIME TO WRITE ALL THAT, THEN WRITE THE FUCKING LETTER YOURSELF! THIS MAKES NO SENSE!"
