Here are some ideas:
1. You are headed somewhere nice and sunny. It's a foreign country so your in the mood for a foreign book. How about 13 Little Blue Envelopes by Maureen Johnson. It's cute, fun and flirty wrapped in one book.
2. Your stuck at home with your boyfriend and are in the mood for some hot and steamy teen romance. How about an almost classic like Forever by Judy Blume. It's fun, sweet and sassy in oh-so-many juicy ways.
3. Road Trip with the girls! Your in the mood for something strong in the friendship zone... How about Someone Like You by Sarah Dessen. It will have you laugh and cry all in the same chapter as you discover what best friends are all about.
Tell me what your spring breaks all about and I will recommend a book for that scenario. :)
Hugs and Kisses!
