What books should a teen girl take on holiday?

Okay; so im 13 and female, i am going to Malta this summer and its going to be a relaxing holiday, i was wandering what good books i should take to read by the pool or on the beach, i will be looking to take a few as im going away for 2 weeks. Im a girly girl and love teen girl books, nothing too rude, and i am also in LOVE with the twilight saga. Im not too into action books, i think Twilight is the furthest i go for action;) Thanks, all answers appreciated.
