Going Places (Piper Green and the Fairy Tree, Bk. 4)

Piper Green's class is taking a school trip to China - well, they're taking a pretend trip, on a pretend airplane. So, when the other kids announce they've been on a plane plenty of times. Piper says she has, too. After all, it's just a pretend trip, right? But when Piper gets chosen to be a flight attendant, her little fib suddenly feels like a very big problem. Could the X-ray vision glasses Piper found in the Fairy Tree help her out?
