Fisher's book, "The Princess Diarist," was on top of Amazon's list of best-selling books today, just ahead of "Zero Sugar Diet."
"Wishful Drinking" and "Postcards From the Edge" were also in Amazon's top 10, with "Shockaholic" ranked as No. 57. Five of the top 10 books on Amazon's "Movers and Shakers" list, which measures titles that show the greatest upward movement in sales over a 24-hour period, were by Fisher.
