Diana Peterfreund Books in Order (Updated May 10, 2026)

Diana Peterfreund writes across adult fiction, young adult fantasy, middle grade adventure, YA mystery, Austen-inspired science fiction, tie-in fiction, short stories, and nonfiction essays. Her books are not one shared universe, so the right reading order depends on which part of the catalogue you are choosing.

Diana Peterfreund Books in Order (Updated May 2026)

The cleanest path is to read each series separately. Secret Society Girl, Killer Unicorns, For Darkness Shows the Stars, Omega City, The Clue Mysteries, and Ellen Poe each have their own continuity.

Secret Society Girl / Ivy League Books in Order

This is Peterfreund’s adult campus series about Amy Haskel and an elite secret society. Read these in order because Amy’s initiation, relationships, and senior-year arc build across the four books.

  1. Secret Society Girl (2006): Amy Haskel is tapped for a powerful Ivy League secret society, forcing her into a world of old money, hidden rules, and campus politics.
  2. Under the Rose (2007): Amy’s place inside the society becomes more complicated as loyalty, secrecy, and reputation start carrying larger personal costs.
  3. Rites of Spring (Break) (2008): The third book pushes Amy’s secret-society life into spring-break chaos, where friendships, romance, and danger collide.
  4. Tap & Gown (2009): Amy reaches the final stage of her college arc, with graduation, society obligations, and emotional loose ends coming together.

Killer Unicorns Books in Order

The Killer Unicorns series should be read in order. The short stories are optional, but they expand the world around the two main novels.

  1. Rampant (2009): Astrid Llewelyn discovers that unicorns are not gentle creatures but deadly monsters, and that her family history ties her to the women trained to hunt them.
  2. Ascendant (2010): Astrid’s battle against killer unicorns continues as the cost of hunting, power, and loyalty becomes harder to ignore.
  3. Errant (2011): A short Killer Unicorns story that works as supplemental reading after Rampant and Ascendant.
  4. The Care and Feeding of Your Baby Killer Unicorn (2011): A short story connected to the Killer Unicorns world, best read as an extra rather than a required installment.
  5. The Lion and the Unicorn (2012): A further short piece in the same fantasy mythology, useful for completists after the main books.
  6. On a Field, Sable (2014): A later Killer Unicorns-related short story, best treated as bonus material for readers who want the wider mythology.
  7. The Hammer of Artemis (2015): A connected short story in the Killer Unicorns setting, placed late because it belongs to the expanded short-fiction side of the series.

For Darkness Shows the Stars Books in Order

This series is a post-apocalyptic, science-fictional Austen retelling sequence. For Darkness Shows the Stars draws from Persuasion, while Across a Star-Swept Sea is a companion novel with a different central story.

  1. Among the Nameless Stars (2012): A prequel novella following Kai before the events of For Darkness Shows the Stars, useful after you already know the main novel’s emotional stakes.
  2. For Darkness Shows the Stars (2012): Elliot North and Kai’s story reworks Persuasion in a future world shaped by genetic disaster, class division, and forbidden technology.
  3. The First Star to Fall (2013): A short prequel to Across a Star-Swept Sea, showing the political rupture that helps create that companion novel’s world.
  4. Across a Star-Swept Sea (2013): A companion novel inspired by The Scarlet Pimpernel, shifting focus to Persis Blake and a society caught in rebellion.

Best For Darkness Shows the Stars Reading Order

For new readers, read the main novels before the prequels.

  1. For Darkness Shows the Stars (2012): Begin here because it introduces the world and emotional logic of the series.
  2. Among the Nameless Stars (2012): Read next to see Kai’s earlier perspective without weakening the first book’s mystery.
  3. Across a Star-Swept Sea (2013): Move to the companion novel after understanding the broader setting.
  4. The First Star to Fall (2013): Read last as background material for Across a Star-Swept Sea.

Omega City Books in Order

The Omega City books are middle grade adventure novels. Read them in order because each book follows Gillian Seagret and the continuing secrets around the lost Cold War-era city.

  1. Omega City (2015): Gillian Seagret follows her father’s theories about a lost underground city and discovers that the mystery is more real than anyone believed.
  2. Omega City: The Forbidden Fortress (2017): Gillian’s adventure continues as new family pressure and hidden technology raise the stakes around Omega City.
  3. Omega City: Infinity Base (2018): The series finale brings the secrets of Dr. Underberg, Omega City, and the children’s discoveries toward resolution.

The Clue Mysteries in Order

This YA mystery trilogy is inspired by the classic board game Clue. Read the books in order because the Blackbrook Academy murders and character secrets carry forward.

  1. In the Hall with the Knife (2019): A storm traps students at Blackbrook Academy, where a murder turns familiar Clue-style names and weapons into a modern YA mystery.
  2. In the Study with the Wrench (2020): The second mystery follows the fallout from the headmaster’s murder as a new semester brings new secrets and another death.
  3. In the Ballroom with the Candlestick (2021): The trilogy concludes as the surviving students face another tragedy and the final shape of Blackbrook’s secrets.

Ellen Poe Books in Order

Ellen Poe is Peterfreund’s newest YA series. It should be read in order because the first book establishes Ellen’s connection to Edgar Allan Poe’s legacy and the supernatural rules around it.

  1. Ellen Poe: The Forgotten Lore (2026): Ellen Poe, a descendant of Edgar Allan Poe, begins confronting ghosts, nightmares, and the unsettling inheritance attached to her family name.
  2. For Evermore (2026): The second Ellen Poe book is scheduled after The Forgotten Lore, so it belongs next in the series and should be treated as upcoming until release.

Standalone Novel

  • Morning Glory (2010): A novelization tied to the film about Becky Fuller, an ambitious morning-show producer trying to rebuild her career and manage a chaotic broadcast world.

Children’s / Graphic Anthology Work

  • Animal Rescue Friends: Learning New Tricks (2022): A contributor volume in the Animal Rescue Friends line, best treated as shared-world children’s material rather than a Diana Peterfreund series installment.

Short Story Anthologies and Collections

These are optional for most readers. They contain Peterfreund stories or contributions, but they are not usually required for the main series order unless noted above.

  1. Zombies vs. Unicorns (2010): Includes Killer Unicorns-related material and is most relevant after Rampant.
  2. Kiss Me Deadly (2010): A paranormal YA anthology with a Peterfreund contribution, useful only for short-story completists.

  14. Appalachian Strong (2025): A charity anthology benefiting survivors of Hurricane Helene, relevant only for completists tracking all contributor appearances.

Nonfiction and Essay Contributions

These are not novels and do not belong inside the fiction reading order.

  1. Everything I Needed to Know About Being a Girl I Learned from Judy Blume (2007): A personal essay anthology about Judy Blume’s influence, with Peterfreund as a contributor.
  2. Through the Wardrobe (2008): A Narnia-focused essay collection including Peterfreund’s nonfiction contribution.
