It contains no new essays. The lead essay "Reflections on Enchantress from the Stars" deals with issues that the author feels readers of the novel should be aware of. The other essays in this book are about subjects relevant to the story such as the importance of space exploratiom, outlook toward the future, and the reality of psi powers. They include: Reflections on Enchantress from the StarsPerspective on the Future: The Quest of Space Age Young PeopleFaith as the Focus of Children of the StarUpdate on the Critical Stage: The Far Side of Evil's Relevance TodayA Response to Some Reactions to Journey Between WorldsSpace and Human SurvivalBreaking Out from Earth's ShellWhy There Will Never Be an Interplanetary WarThe Role of Psi in Human AffairsThe Roots of Disbelief in Human Mind PowersTranshumanism Is a Dead EndWhy I Don't Read Much Science Fiction

Starship pilot Terry Radnor is elated to be among those chosen to defend the secret colony Maclairn against enemies who pose a threat to the spread of paranormal human mind powers. He commits himself wholly to the goal of that world, not guessing how far his effort to protect it will take him from everything else he cares about--his promising career as a Fleet officer, contact with people who share his newly-discovered psi capability, his wife and unborn child. Torn away against his will after learning a secret too deep for its disclosure to be risked, he is forced into exile from all that has previously mattered to him, and must build a perilous new life far from Maclairn, grounded without hope of fulfilling his earlier pledge. Yet a mysterious and extraordinary destiny has been predicted for Terry, and against all odds fate puts him in place to confront the colony's greatest peril. This is the first book in the Rising Flame trilogy, but is complete in itself and can be read alone. Set two centuries later in time than the Hidden Flame duology--consisting of Stewards of the Flame and Promise of the Flame, which tell of the founding of Maclairn--it is an independent and quite different story that in no way depends on having read them. Please note that unlike Engdahl'e YA novels, all five of these are adult novels and contain some material inappropriate for readers below high school age.

On completion of her training as an agent of the interstellar federation's Anthropological Service, Elana is sent to a world whose people may soon destroy their civilization. Since not enough is understood about the situation to justify any interference with their evolution, the Service has no power to act; its agents must go as helpless observers, posing as natives, in the hope of gaining knowledge that may help to save other worlds. This passive role proves intolerable to the young, inexperienced agent assigned to the same city as Elana, a city under totalitarian rule. After falling in love with a local girl who has become Elana's closest friend, he identifies too completely with the natives and unwittingly endangers the entire world by a well-meant but ill-advised attempt to intervene. Forced to assume responsibility for undoing the damage, Elana finds that only she-at great cost-can prevent an immediate war of annihilation. Although this novel has the same heroine as the author's Newbery Honor book Enchantress from the Stars, it is not a sequel but a completely separate-and very different-story not intended for readers below high school age, which is also enjoyed by adults. The two books are in no way dependent on each other and can be read in either order.

As captain of his own starship Estel, Terry Steward, born Terry Radnor, is committed to spreading acceptance of psi powers and other advanced mind capabilities throughout the colonies of humankind. Barred from contact with his beloved planet Maclairn, he now journeys from world to world, heralding the hopeful future about which he alone knows the full truth. But the opponents of mind-powers are gaining strength, and on Earth the persecution of people who develop such abilities is increasing. Soon targeted by bounty hunters, Terry risks everything that matters to him in a desperate attempt to defeat Maclairn's enemies, not guessing that if he lives long enough, he is destined for an even greater role in human history than he has played as a defender of its cause. This is the second book in the Rising Flame trilogy. Though it is complete in itself and can be read alone, the first, Defender of the Flame, should be read before this one for fuller understanding of the hero's past experiences. Set two centuries later in tme than the Hidden Flame duology--which tells of the founding of Maclairn--it is an independent and quite different story that in no way depends on having read them. Please note that unlike Engdahl's YA novels, all five of these are adult science fiction and contain some material inappropriate for middle-school readers.

An omnibus edition containing the complete trilogy This Star Shall Abide (known in the UK as Heritage of the Star, Beyond the Tomorrow Mountains, and The Doors of the Universe. Noren can see that his world is not as it should be--it is wrong that only the Scholars, and their representatives the Technicians, can use metal tools and Machines. It's wrong that only those few have access to the impenetrable City, which he has always longed to enter. Above all, it is wrong for the Scholars to have sole power over the distribution of knowledge. Unable to believe in the Prophecy that promises these restrictions will someday end, he declares it to be a fraud and defies the High Lew under which they are enforced. His family and the girl to whom he is betrothed reject him. Yet he cannot turn back from the path that leads him to the mysterious fate awaiting heretics. But the more he learns of the grim truth about his people's deprivations, the less possible it seems that their world can be changed. And once he discovers what really happened in their past, he becomes convinced that it is up to him to restore their rightful heritage. To do so, however, will mean giving up all else that matters to him, for it will demand more drastic steps than anyone has imagined. Of the hardover editions of these novels Kirkus Reviews said, "The fascination of both [the first two] volumes lies in Engdahl's ability to create a many-layered society with a tragic past and a doubtful future that depends on its ability to cope with a harsh, brutal environment." The three were "originally marketed as young adult books, but there is nothing juvenile about them," said the San Jose Mercury News when they were republished in one volume as adult science fiction. "Engdahl tells an important and pertinent story,"

Melinda Ashley has a plan for her life, and a trip to Mars isn't part of it. When she receives a spaceliner ticket as a high school graduation gift from her dad, she is dismayed, but reluctantly agrees to go with him--in part because she's infuriated by her fiance's high-handed declaration that she can't. Her outlook begins to change when she meets Alex Preston, a second-generation Martian colonist who is going home after college on Earth. Alex believes settling Mars is important. He's looking forward to the role he expects to play in the colony's future. Melinda finds this hard to understand, yet she is more and more drawn to him and, while on Mars, to his family. Torn between what she has always wanted and upsetting new feelings, she wonders if she can ever again be content. It takes tragedy and a terrifying experience on the Martian moon Phobos to make her aware of what really matters to her. The National Space Society's book reviews called this novel "A must-read for all future space pioneers who wish to persuade their friends to join them in making that future journey between the worlds of the known and the unknown." The Wichita Falls Times described it as "absorbing science fiction ... Intensive first-person characterizations and a love story one can really care about." Although it's set on Mars, it's not about space technology or exotic adventure. It's centered on the experiences of ordinary people and is usually enjoyed more by readers who like romance than by avid science fiction fans. While intended for Young Adult readers, adults also enjoy it. A reviewer for Romance Junkies called it "captivating and thought provoking. There's much more to this book than romance or a coming of age type of story, but instead the concepts it holds are what make it appealing."

Ardith Moran is elated by the prospect of contact with extraterrestrial civilizations, elated enough to stake her life on her conviction that they exist after the exploratory expedition's leaders turn back. The last thing she expects is to fall in love with an alien, much less for their love to play a key role in saving Earth from tyranny and eventual ruin. As a member of the Anthropological Service, he is willing to make sacrifices and expects her to do the same. Can she, influenced by the legacy of the now-legendary Captain of Estel, convince Earthborn people that they can't retreat from the universe? Or will Earth's authorities succeed in killing her to suppress the evidence only she and her fellow envoys can provide? The first two bools in this trilogy, Defender of the Flame and Herald of the Flame, need not be read before this one, as it is complete in itself. However, the backstory it contains includes major spoilers for them. Please note that unlike Engdahl's YA novels, these are adult science fiction and contain some material inappropriate for readers below high school age.
