"Punker Pursuit" is one of the most daring experiments ever conducted in science fiction by the legendary author of the classic bestseller "Starship Troopers". Earth under threat of alien invasion. Only four people know this and can prevent a tragedy. But the heroes fall into the trap of sinister aliens, and they have the only way to escape from the pursuit - to leave this plan of being on their space yacht and find themselves in a parallel universe. Until this point, the novel is similar to the famous "Number of the Beast", but after - all the storylines diverge, the characters find themselves in the universes of "Punker Chase": the worlds of Edgar Rice Burroughs, Frank Baum and the father of space opera E. E. "Doc" Smith . A fitting farewell from one of the most inventive science fiction writers ever to live: a parallel novel about parallel universes, as well as a great adventure in which the forces of good confront evil only in a way that only Heinlein could. “This is an old-school Heinlein novel: the writer we all loved took us on another great trip. For those of us who love the reckless Heinlein of early times, with characters more competent than they are in life, and witty "in the style of crazy comedy" dialogue, this lost pearl is simply necessary. Robert Sawyer “The previously unpublished book of Grandmaster Robert Heinlein will be in demand by his many fans and readers interested in the history of the genre. The novel is based on the same premise and contains the same characters as his Number of the Beast. Indeed, the beginning of the book is identical. But then the text goes into a completely different story, which is quite appropriate, since the books are based on journeys on alternative worlds. As in The Beast, our intrepid explorers travel through various fictional universes: the Burroughs Barsum, the Land of Oz Baum, the Lensman universe of Smith's Dock, facing the idea that all fictional universes exist somewhere in the multiverse. Booklist“Interpersonal relationships, sexual tension and joyful arousal plenty. Family hierarchies or social worship of them resemble the morality of the fifties, but not to such an extent as to be asphyxiating. In any case, they are skillfully used to maintain a love conflict. I won't say anything more; all of Heinlein's fans deserve to experience this wonderful return themselves." Manhattan Book Review
