Mood

The mood the book leaves you in.

  • The reading experience is propelled by journeys, exploration, and physical risk; excitement and forward momentum dominate over dread or introspection.
  • Joy and loss are deliberately mixed; the resolution grants characters something real while taking something else away, leaving warmth and sorrow together.
  • The book demands work from the reader — dense prose, difficult structure, unfamiliar ideas, or morally uncomfortable material — as part of its intended effect.
  • Grim events, cruelty, or despair dominate the atmosphere, and the book does not soften them with comfort or comic relief.
  • The atmosphere is quietly unsettling — wrongness, unease, and the uncanny pervade the book without necessarily escalating into overt horror.
  • The book is built to move the reader; character feeling is foregrounded and major scenes aim at a strong emotional response.
  • Humor is a primary aim and the prose plays for laughs — comic situations, wit, or dialogue produce sustained comedy, not occasional levity.
  • The book insists that things can improve; effort and decency are shown to matter, and the arc bends toward better outcomes even through hardship.
  • The book teaches as it goes — real facts, history, science, or craft are conveyed in enough depth that learning is part of the reading experience.
  • The book is designed to uplift and motivate, presenting perseverance or achievement in a way that invites the reader to aspire or act.
  • The overall register is cheerful and easygoing; stakes are kept gentle and the book avoids dwelling on pain or dread.
  • Withheld information drives the experience; the book sustains enigmas and secrets the reader wants resolved, whatever its genre.
  • The book is contemplative and inward-looking, giving more weight to thought, memory, and meaning than to external events.
  • The book works as comfort reading — low tension, a soothing pace, and an atmosphere the reader can unwind in.
  • Grief, loss, or melancholy set the dominant register, and the book lets sorrow stand rather than resolving it into comfort.
  • Sustained suspense is the point; the book keeps the reader braced for what happens next through danger, pressure, or impending revelation.
  • Playful invention and charm define the register — fanciful conceits, light absurdity, and a narration that delights in its own oddity.

About

What the story runs on.

  • Stories in which extraterrestrial beings are central — as characters, cultures, or the object of the plot.
  • Stories structured as a quest — a journey undertaken to find, deliver, or destroy something of great import.
  • Stories in which staying alive against nature, catastrophe, or scarcity is the central problem.
  • Stories of lovers kept apart by law, family, faith, or station, where the obstacle to love is the plot.
  • Stories in which a friendship — its making, testing, or loss — is the emotional center.
  • Stories of growing up — a young protagonist crossing from childhood into adult knowledge and responsibility.
  • Stories about who a character truly is — self-discovery, doubled lives, and the search for a self.
  • Stories about mourning — living through the death of a loved one and what loss does to the survivors.
  • Stories in which a buried family truth — hidden parentage, crimes, or shames — surfaces and reorders the present.
  • Stories driven by maneuvering for power — factions, conspiracies, and statecraft conducted in shadow.
  • Stories in which war itself is the subject — combat, occupation, and what warfare does to soldiers and civilians.
  • Stories organized around investigating a killing — the case, the clues, and the pursuit of the killer, in any genre's clothing.

                  From the flaps of the Del Rey first edition: "Hal Cousins is one of a handful of scientists nearing the most sought after discovery in human history: the key to short-circuiting the aging process. Fueled by a wealth of research, an overdose of self-confidence, and the money of influential patrons to whom he makes outrageous promises, Hal experiments with organisms living in the hot thermal plumes in the ocean depths. But as he journeys beneath the sea, his other world is falling apart. Across the country, scientists are being inexplicably murdered - including Hal's identical twin brother, who is also working to unlock the key to immortality. Hal himself barely eludes a cold-blooded attack at sea, and when he returns home to Seattle, he finds himself walking into an eerie realm where voices speak to him from the dead ... where a once-brilliant historian turned crackpot is leading him on a deadly game of hide-and-seek ... and where the beautiful, rich widow of his twin is more than willing to pick up the pieces of Hal's life-and take him places he's never been before. Suddenly Hal is trapped inside an ever-twisting maze of shocking revelations. For he is not the first person to come close to ending aging forever - and those who came before him will stop at nothing to keep the secret to themselves. Now every person on earth is at risk of being made an unsuspecting player in one man's spectacular and horrifying master plan. From the bottom of Russia's Lake Baikal to a billionaire's bionic house built into the cliffs of the Washington seashore, from the darkest days of World War II and the reign of Josef Stalin to the capitalist free-for-all that is the United States, Vitals tells an astounding tale of the most unimaginable scientific secret of all - exposed by the quest for immortality itself..."

                  Publisher's description: "s violence a virus? Can your genes make you a killer? Why are we so willing to hurt each other? In The Babel Effect, the brilliant husband-and-wife research team of Ryan and Jessamine McCloud are charged with answering these urgent questions. Beginning as a neurological study of murderers on death row, their research explodes into an investigation into the biomedical foundations of human history. The quest takes them from prison cells to research labs to war zones throughout the world and forces them to doubt their most basic assumptions about the human species, about themselves, and about their marriage. Combining systems theory with modern epidemiology, they soon learn that our propensity for violence resembles a contagious disease. But is the human carnage of the last hundred years an ancient plague or a new nightmare? Can they identify the cause and find a cure? As their discoveries reveal frightening secrets about multinational corporations, clandestine military programs, and millennial religious cults, they realize that finding the answers depends on a still more urgent and terrifying question: Can they survive the search? When an unknown enemy steals their data and abducts Jessamine, the FBI investigation stalls, and Ryan realizes that it is up to him alone to find his pregnant wife. He soon finds that to learn where she is, he must discover who she is -- and confront the question of whether we can ever really know the one we love."

While he still has his health, Pierre and his wife decide to have a child, and they search for a sperm donor. When Pierre informs Dr. Klimus of their plan, Klimus makes an odd but generous offer: to be the sperm donor as well as to pay for the expensive in vitro fertilization. Shortly thereafter it transpires that Klimus might be hiding a grim past: he may be Ivan Marchenko, the notorious Treblinka death-camp guard known as Ivan the Terrible. While digging into Klimus's past with the help of Nazi hunter Avi Meyer, Pierre and his wife discover that Pierre's insurance company has been illegally screening clients for genetic defects.
