What stands out

  • Its median reviews are 8% of the parent category Science & Nature (120), one of the easier corners under it.
  • Its review barrier is lower than in 81% of Kindle eBooks categories: the median best seller has only 10 reviews, so new books can chart with few.
  • Prices spread wide: the middle half runs from $4.99 to $10.99, so budget editions and premium or boxed sets sell side by side.
