Summarise Genre Conventions for a New-to-Genre Writer

You want to write in a genre you have barely read, which is a fast route to getting it wrong. This gives you a practical orientation: the genre's origin and reader promise, the five conventions you must understand, the three beginner mistakes, and the vocabulary agents and editors actually use. A crash course before you start.

I want to write my first {GENRE} novel but I've read very little in the genre. Give me a practical orientation covering:

1. The genre's origin and the reader promise that defines it
2. The 5 most important conventions I must understand (not necessarily follow)
3. The 3 most common beginner mistakes writers make when entering this genre
4. Key vocabulary and terminology used by editors, agents, and readers in this genre
5. A recommended reading list of 6 titles: 3 that exemplify the conventions and 3 that successfully subvert them

Keep explanations clear and assume no prior knowledge of {GENRE}. Format as a structured orientation guide I can reference while drafting.
