1) What Alice Forgot by Kate Moriarty: I actually found this book quite thought-provoking, but Alice's character was hilarious and it was not heavy enough to leave me in a mess, so probably a good beach read.
2) Water for Elephants by Sara Gruen: I read this on my last vacation too. It's a bit ridiculous at times, but a fun read. I mean, there are circus elephants in it, what's not to love?
3) The Eyre Affair by Jasper Fforde: So silly and fun.
4) Georgiana Darcy's Diary by Anna Elliott: Obviously this pales in comparison to Austen herself, but it's a light-hearted return to my beloved Pemberley, and it made me smile a lot.
5) Attachments by Rainbow Rowell: Beth and Jennifer's emails made me laugh out loud, and this is a quick read for a few days at the beach.
6) Confessions of a Shopaholic by Sophie Kinsella: At first, I didn't like this book and found Becky annoying, but she did grow on me, and this is a fun, light read for summer.
7) To Say Nothing of the Dog by Connie Willis: Punting! Mediums! Time travel! A fun read guaranteed to make you laugh at least once.
8) The Shell Seekers by Rosamunde Pilcher: A bit heavier than some of the above, but a real epic, romantic read.
9) Northanger Abbey by Jane Austen: A good holiday read because a) it takes place during a holiday; b) the satire is hilarious; c) there's a happy ending (I feel like that's not a spoiler since it's Austen).
