Publish your book(s) with us!

It can be challenging for writers and even existing authors to get noticed in front of publishers. That's why we created an easy to navigate and straightforward online submission system. Since 2020, our system has allowed authors of all genres to have their work considered by one of our editors. Please note that 5310 Publishing only accepts unsolicited manuscript submissions through our electronic system, do not email us.



We currently have THREE submission forms.

Please read our instructions and use the correct one when applying.

Please only submit one manuscript at a time!

Manuscript Common Themes & Tropes

Your book doesn’t need any of those elements to qualify, but if you have any of them, please mention it in your query letter. But again, it is not a requirement.

  • Romance with Artificial Intelligence, Aliens, Between Worlds, etc.

  • Stories with a Black main character (we really really really want a black or person of colour as the main character)

  • Stories that explore subjects like racism, homophobia, etc.

  • A story with a transgender character (main or secondary).

  • A story with a character with a disability (main or secondary character with autism, dyslexia, ADHD, BDD, mobility, visual, hearing, learning, or other)

  • Conspiracy theories

  • A story where the main character falls in love with the unnoticed

  • Science and Technology, Fringe Science, Parallel universes, Time Travel, Weird but Interesting stuff (Comparable TV shows: Fringe, Lost, Revolution, The 100, Timeless, FlashForward, Continuum)

  • Worlds where technology took over (Comparable TV shows: Black Mirror, Upload)

  • Locked room thriller, psychological thriller, suspense thriller.

  • Dinner Party Murder Mystery Trope

  • Reverse damsel in distress (she saves him).

NOTE: Having one of those tropes as part of your story is not a requirement. Even if you don't have any of them, your book still qualifies and you may still get a publishing offer. These are just some examples.

A Note on Book Banning

If you think your book will be banned in Texas, or in any other state, then absolutely query with us! The U.S. has a book-banning problem, and that shouldn’t stop you from publishing your book around the world. Books are meant to be challenging. We want to question harmful stereotypes and explore ideas that are so far unexplored. We want to break barriers. Books should talk about gender, race, and sexuality; and authors shouldn’t be afraid of exploring those issues.


What we don't want


  • If your book is over 140K words.

  • If your book is incomplete or not edited.

  • If you are homophobic, misogynist, xenophobic, ageist, etc., or your story is about those types of people, don’t bother applying. You will be rejected. (For example, Neonazi Romance)



  • 5310 Publishing currently does not assess erotica, horror, scripts, or comic books.

  • We do not consider short story collections, anthologies, poems, or individual stories.

  • We do not publish Middle Grade, Picture Books, or Children’s books.

  • We do not re-publish disputed titles or titles from other publishers.

  • We do not re-publish self-published titles (Kindle and Wattpad included.)



  • Books with weird / ultra-exotic names, especially the main characters. (e.g., Axwhyzee, Elrohire, Grimvenger, etc.)

  • Steampunk, high fantasy, epic fantasy, sorcery, Wiccan, pagan, and horror.

  • Stories mainly about witches, vampires, werewolves, zombies, and dragons (although it’s okay if they exist in the world as side characters and the plot is about something else that doesn’t revolve around them.)

  • During this submission round, we are not looking for Weird West & Western Fantasy, Dark Fantasy, Gothic, Sports Fiction, Erotica, detailed police procedurals, legal thrillers set in courtrooms, and Military Fiction (but we do want Sci-fi Military).



  • Please read all of our instructions and guidelines on this page to make sure your manuscript fits what we are currently looking for before you send your manuscript.
