In Search of the Time and Space Machine — Deborah Abela

Max Remy is eleven and bored with her life. Her father went off to Hollywood and ends up married to a movie star and Max is left with her mother who works, works, works all the time. So Max invents Alex Crane, a super spy, and begins to fantasize about the life of a spy. Then horrors: Max's mother sends her off to live with her aunt and uncle on a farm for the entire summer. Dull, you think. But then she stumbles into a real spy ring, and uses her wits to outsmart the evil Mr. Blue. Max Remy is now a card-carrying member of the international organization Spy Force and the adventure has just begun.
