Under the Sea — Mimi Strong

Mr. Thorne's been talking to Lexie's best friend, and now there are plane tickets booked for Friday.

Lexie buys some special underwear for the trip, but that's not all she's bringing. She's got her best friends in tow with her, and they're all going diving, under the sea.

The resort is halfway around the world, and despite having the time of her life, Lexie finds herself thinking about someone back home.
