Sweet Valley Confidential: Ten Years Later by Francine Pascal- I loved this series growing up, but it was just a bad idea to pick this up. Obviously I knew it wouldn't be amazing or even well-written, but I had a previous connection to the characters, and wanted a beach read for my California vacation. It was just a bad idea all around. This review at the book blog Stacked says it all. I agree with her completely, but would go one step further. I wouldn't even recommend it if you were a Sweet Valley reader in the past.
This Girl Is Different by JJ Johnson- I'm interested in homeschooling, plus I love to read anything that's not mainstream culture. When I saw this book on Netgalley, I requested it and thought I would really enjoy it. The portrayal of homeschoolers was too stereotypical, and the ending was just too perfect.
