Book Trilogies to Start, Grouped by Genre

Fourteen trilogy openers in four genres, with content notes.

By · Updated October 15, 2026 · 6 min read · 14 books

The Hunger Games, The Fifth Season, and The Poppy War are three places to start, covering dystopia and epic fantasy. Each one is the first book of a trilogy.

At ReadNext, we group these fourteen trilogy openers into four genres: fantasy, science fiction, dystopian, and literary and thriller. Each title carries an audience label and a content note where the material is heavy, so you can filter before you start.

This page is for readers who want a story told across three books rather than a single novel.

Choosing by Audience and Content

Every title here carries an audience label of adult or young adult. Five books here are young adult novels: The Cruel Prince, The Hunger Games, Divergent, The Maze Runner, and Delirium. The other nine are adult novels, so read the label first and then the content note in each blurb.

Sexual content appears in both adult and young adult titles here, so the audience label alone does not settle the question for a sensitive reader.

Matching a Trilogy to Your Genre

Four groups organize the list. Pick the group that matches the kind of story you want, then compare the three to four titles inside it.

  • Fantasy: The Magicians, The Cruel Prince, The Fifth Season, and The Poppy War.
  • Science fiction: Ancillary Justice, Dawn, and Red Mars.
  • Dystopian: The Hunger Games, Divergent, The Maze Runner, and Delirium.
  • Literary and thriller: City of Glass, Men at Arms, and The Passage.

Length and Commitment

Every title here is the first book of a trilogy, so the commitment is three books rather than one. Plan for the full run before you start a title you may not finish.

The Hunger Games and Divergent both carry violence notes, so check the content note before you begin.

When a Pick Does Not Land

Putting a book down after a few chapters is a reasonable choice. It does not commit you to the other two books in that trilogy.

Switch groups instead of forcing the same genre. If you are unsure which genre suits you, the What should I read quiz on this site can help narrow the options. For more fantasy beyond the four fantasy openers here, see fantasy books for adults and dark fantasy books.

Content Notes for Parents and Teachers

Dawn lists sexual content, violence, coercion, and body-horror themes. The Fifth Season lists graphic violence, child abuse, sexual assault, and slavery. The Poppy War lists graphic war violence, torture, sexual assault, and drug use. The Passage lists graphic violence, horror, and the deaths of children. The Magicians lists explicit sex, drug use, graphic violence, and profanity.

For a sensitive reader, preview these books before handing them over. The Hunger Games lists child deaths in televised combat, and The Maze Runner lists gore, so read those two alongside a parent or teacher if violence is a concern. If your reader wants a read-alike for adults, see books like The Hunger Games.
