The Disappearing TV Star (Unabridged‪)‬

From the author of the Deltora Quest series comes a classic children's series in the tradition of The Famous Five.
Richelle is delighted when the Teen Power gang is hired to be extras in a TV commercial for a new candy bar called The Lot. Is this her big break? Her chance to get into modeling or the movies? At last they've found a job that's interesting, and trouble-free.

But her plans for this glamorous new job don't include getting mixed up with spoilt teenage millionaire TV star Cassandra Cass.
