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 about venturing into space to explore — survey missions, astronauts, and the frontier of the unknown beyond Earth.
  • 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 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.

    • Fantasy that blends in horror's atmosphere and imagery, keeping a fantastical frame around grim or frightening material.
    • Action-driven fantasy following warriors or rogues with personal stakes against sorcerous threats, rather than world-spanning conflicts.
    • Fantasy set in a real historical period or a close analogue of one, with magic woven into the era.
    • Fantasy in which protagonists cross from the ordinary world into another world through a portal or similar passage.
    • Fiction that retells or reworks a traditional fairy tale in a new form or setting.

      • Horror of decaying houses, buried family secrets, and oppressive atmosphere in the Gothic literary tradition.
      • Horror centered on hauntings and the returning dead.
      • Horror located in the mind — paranoia, obsession, and unreliable perception rather than external monsters.
      • Horror built around the reanimated dead and survival amid their outbreaks.
      • Horror defined by explicit, transgressive gore that refuses to cut away from violence.
      • Speculative fiction of the strange and uncanny that resists both natural explanation and standard genre categories.
      • Fiction organized around solving a crime or puzzle, typically following an investigator toward the identification of a culprit.
      • A puzzle-first mystery that lays out clues so the culprit's identity can be deduced before the reveal.
      • Crime fiction of moral ambiguity, fatalism, and hard-edged style, set among the corrupt and the doomed.
      • A mystery following the realistic routines of police work — forensics, interviews, and case-building.
      • A gentle mystery with an amateur sleuth, a small community, and violence kept off the page.
      • A mystery set in a past era, where the investigation works within that period's methods and society.

          • Fiction written primarily to amuse, using comedic situations, wit, or parody as its organizing principle.

                  From the back cover of the first DAW printing: "Out of their minds and the force of their imagination, men have created countless beings, from demons and dragons and monsters of legend to story-book heroes and comic strip characters. What if their world were real - if vampires, devils and Don Quixote hobnobbed with Dagwood Bumstead and Charlie Brown. Such a world would have its fascinations... and its dreadful perils - if it existed. Horton Smith found out that it did exist... and that he was right in the middle of it!"

                  Jerry Cornelius is a fictional character created by English author Michael Moorcock. The character is an urban adventurer and an incarnation of the author's Eternal Champion concept. Cornelius is a hipster of ambiguous and occasionally polymorphous gender. Many of the same characters feature in each of several Cornelius books, though the individual books have little connection with one another, having a more metafictional than causal relationship. The first Jerry Cornelius book, The Final Programme, was made into a 1973 film starring Jon Finch and Jenny Runacre. Notting Hill in London features prominently in the stories.

                  Dirk Gently's Holistic Detective Agency (1987) introduces Douglas Adams's eccentric investigator, whose approach treats all events and objects as ultimately connected however implausibly, as a case involving time travel, a ghost, and a Cambridge murder tangles into one plot. Adams completed one further full novel, The Long Dark Tea-Time of the Soul (1988), before his death; The Salmon of Doubt (2002) later collected his unfinished notes toward a third book alongside essays and other writing, rather than completing the story.

                  Two separate modern continuations of E. Nesbit's Psammead stories were written decades apart by different authors: Helen Cresswell's The Return of the Psammead (1992) brings the wish-granting sand fairy back for a new set of children, while Kate Saunders's Five Children on the Western Front (2014) follows the now-grown Lamb and his siblings as the First World War arrives, in a more somber sequel to Nesbit's original trilogy. Neither book is by Nesbit herself, and the two have no direct connection to each other beyond both drawing on her creation. Later writers have kept returning to Nesbit's premise long after her own trilogy ended.

Fforde has extended the sequence across eight books and several decades, with further installments in the works.
