Reports about placement are improving enormously. It’s amazing how merely being on the NYT list didn’t have this effect, but being #1 makes it much more difficult for stores to hide it. But not impossible. From a reader:

I purchased your book yesterday at a Border’s Books in Costa Mesa , CA. They told me it was a best seller but we couldn’t find it on the BS table. I followed the clerk through the store and we finally found it stacked on the floor in a back corner niche. Thought you and your publisher should know.
