If you've never written a hot premise, and are intimidated by the thought of trying, here is the method I follow to generate them:

1. Give your protagonist a two or three word situational, professional and/or emotional tag, i.e.:

Renegade cop

Bioengineered surgeon

Convent-schooled heiress

2. Define the protagonist's actions and objectives:

Renegade cop hunts former lover

Bioengineered surgeon flees domineering creator

Convent-schooled heiress marries destitute noble

3. What's the ultimate goal?

Renegade cop hunts former lover to catch an arsonist turned killer.

Bioengineered surgeon flees domineering creator and saves alien colony.

Convent-schooled heiress marries destitute noble to escape brutal guardian.

The important thing is not to try to tell the entire plot of the novel in the hot premise, but create a hook that snags interest. There are plenty of ways to write them, too, so you don't have to follow my method.
