Diamonds Are a Teen's Best Friend — Allison Rushby

Nessa Joanne Mulholland, aka Marilyn Monroe's No. 1 teenage fan, is relocating in movie-star style, crossing the Atlantic on a steamer from New York City on her way to Paris.

But when a crush goes terribly wrong, it's clear that Nessa is up to her neck in trouble once again.
