Amazon’s latest book sales chart reveal that J.R.R. Tolkien books now occupy five of the top 20 spots.

The charts for the week of March 27 show the three volumes of The Lord of the Rings in spots #3, #5, and #7, while sales of The Hobbit meant it slotted in at #4. The real surprise, though, is that Tolkien’s posthumously published novel The Silmarillion sold well enough to enter the charts at #12.

Apparently this is the first time that The Silmarillion has reached the top strata of the Amazon sales charts. The result might indicate that Amazon Studios’ Rings of Power series is creating a wider interest in Tolkien’s First Age myths.
