The order the books were released — the default way to read the series.
A historical fantasy departure co-written with Roberta Gellis, the Doubled Edge series reimagines Elizabethan England as a world where the fae realm of Underhill exists alongside the human one, and where historical figures — young Elizabeth I among them — have hidden fae allies shaping the political and magical stakes of the era. Where Lackey's SERRAted Edge books transplant elves into modern car culture, Doubled Edge goes the opposite direction: elves and human history colliding in richly-researched Tudor and Elizabethan settings, blending real court intrigue with fae political machinations.
The four novels — This Scepter'd Isle, Ill Met by Moonlight, By Slanderous Tongues, and And Less than Kind — trace this hidden fae history across roughly Elizabeth I's lifetime and reign, published between 2004 and 2008.
Read in publication order: This Scepter'd Isle (2004), Ill Met by Moonlight (2005), By Slanderous Tongues (2007), And Less than Kind (2008). The series follows a continuous alternate history across Elizabeth I's life and reign, so reading in sequence gives the clearest through-line, though each book also focuses on different court events and periods within that larger timeline.
Four: This Scepter'd Isle (2004), Ill Met by Moonlight (2005), By Slanderous Tongues (2007), and And Less than Kind (2008).
Mercedes Lackey co-wrote all four books with historical fantasy and romance author Roberta Gellis.
Only thematically — both series involve elves interacting with the human world, but they're set in completely different eras (Elizabethan England versus modern-day) with no shared characters or continuity.
Publication order: This Scepter'd Isle, Ill Met by Moonlight, By Slanderous Tongues, And Less than Kind. It follows a continuous alternate-historical timeline across Elizabeth I's life and reign.
Both — it's an alternate history blending real Tudor/Elizabethan political events and figures with a hidden fae world (Underhill) influencing them, making it historical fantasy rather than straight historical fiction.
