Genre Craft

When Breaking a Genre Rule Actually Works

There are two ways to break a genre rule. One is cleverly subverting the form and earning trust. The other is writing the wrong book. Here's how to tell.

Every so often a novel breaks a rule of its genre and it works — it becomes a classic, the rule-break is the book's signature, and everyone tries to copy it. More often, a writer breaks a genre rule and the book just quietly fails. What's the difference?

The two kinds of rule-breaking

Kind one: the rule-break is the point. The author knows the convention, respects it, and has a specific artistic reason for breaking it. The reader notices the break and feels something because of it. The genre is deliberately disrupted.

Kind two: the rule-break is an accident. The author didn't fully understand the convention, got it wrong by default, and the reader notices the break as amateurism. It's the difference between a jazz musician missing a beat on purpose and missing it because they don't know the song.

Most unsuccessful rule-breaks are kind two. Most successful ones are kind one. So the question isn't whether to break rules. It's whether you've earned the right to.

How to earn the right

You earn the right by showing, on page one, that you know the rule you're about to break. Subvert it in a way that could only happen if the author was in control.

Example: in a traditional detective novel, the detective solves the case. A book in which the detective doesn't solve the case is kind two if the reader feels the writer just couldn't figure it out. It's kind one if the failure-to-solve is clearly the book's subject, and the book shows its awareness of the convention repeatedly. “Detective failed to solve it” is a plot hole. “Detective couldn't solve it because the case was about a question mysteries can't answer” is a novel about detection.

The same break, two completely different receptions. The difference is the reader feeling the author in control.

What signals control

  • Characters within the book noticing the convention. The mystery where a character says “this doesn't work like detective stories” is signalling the author knows. You don't have to be this explicit, but some version of the awareness has to leak through.
  • Craft that's otherwise airtight. A book where the sentences are tuned, the character work is strong, and the plotting is deliberate has earned its rule-break. A book where the prose is uneven and the rule-break happens too — the reader reads it as a single failure.
  • The rule-break being set up. If your ending breaks the genre convention, page 50 should have quietly started the setup for that break. Surprises work when they were inevitable in retrospect.

The hardest thing

Writers who've read a hundred genre books tend to know the conventions well enough to break them successfully. Writers who've read ten or twenty don't — they break conventions by accident and wonder why the book doesn't land. This is the unglamorous truth: genre mastery requires reading a lot in the genre. Not twenty books. A hundred. You can't subvert what you haven't absorbed.

Before breaking a rule, make sure you've kept it right in at least three other books. Otherwise you're not subverting — you're guessing.
