Writing styles, an internet quiz

The result I got from analyzing the prologue of The Blood Queen:

I write like
Stephen King

I Write Like by Mémoires, Mac journal software. Analyze your writing!

Versus Chapter 1:

I write like
Dan Brown

I Write Like by Mémoires, Mac journal software. Analyze your writing!

I write like
David Foster Wallace

I Write Like by Mémoires, Mac journal software. Analyze your writing!

Then, just cause I was curious, I analyzed the 2nd chapter of the 2nd book, which has a sex scene in it, and to my amusement, here's the result:

I write like
Harry Harrison
