Bookroo's summary

Frank and Joe Hardy dive into a world where science fiction blurs with reality. Movie director Simon Devoreaux's latest blockbuster has vanished, and the stakes are high. As the brothers navigate a convention filled with Hollywood's finest, they must unravel a mystery that could cost billions. Can they uncover the truth before the fantasy becomes a nightmare?

From the publisher

The aliens are invading! No, they’re not from another galaxy. They’re not even from Mars. They’re from Hollywood! A science fiction convention has come to Bayport, and movie director Simon Devoreaux has lost his billion-dollar baby: the film of his latest blockbuster has dematerialized before his eyes.
