It's been almost five years since Homer's father disappeared. No traces or evidence, as if he had disappeared into thin air! Only his small film studio in the backyard haunts Homer. Especially after one of the actors in dad's film tried to break into her tightly closed doors... Homer Pym and his best friends - Lilya and Sasha - will have to investigate the disappearance of dad without the help of adults: they will never believe it. On his birthday, the boy was given a smart gerbil mouse, which was eager to go to the film studio. She took Homer inside, and the unthinkable was discovered: his father was a prisoner of his own film about the mythical journeys of Odysseus and a parallel world inhabited by extraordinary creatures! Friends will have to show cunning and courage to save him - of course, not without the help of a talking gerbil. Anne Plishota and Sandrine Wolf - authors of the popular series of science fiction books "Oxa Pollock" - have become the creators of another incredible universe full of adventures, mysteries and secrets. If you've been reading the myths of Ancient Greece or dreamed of being in the shoes of the characters in Percy Jackson, this book is definitely for you! Homer Pym is an ordinary 12-year-old boy, not a demigod, not a legendary warrior from ancient Greek myths, but, despite all the obstacles, he becomes a real hero, as in the books “Evan Cartier”, “The Orestes Code” and “The Book of Time”. Together with him you will go on an exciting journey and understand how dear friendship and family really are.
