The Austen Novels

One thing I find odd is that Northanger Abbey was finished in 1798. But then Jane didn't finish Sense and Sensibility until 1811. And from then on, all of her books followed pretty soon, one after the other, with Pride and Perjudice in 1813, Mansfield Park in 1814, and both Persuasion and Emma in 1816. Also, Lady Susan in 1794.

What I'm curious about is why it took her so long between Northanger Abbey and Sense and Sensibility. I mean she was a new author, just starting out and that could have somethign to do with it. But why did it take 13 years to finish another book?

Her father died in 1805, which would make a lot of sense considering Sense and Sensibility was the next book she wrote. Could the death of her father be the reason she stopped writing?
