What Daughters of the Moon by Lynne Ewing Actually Is
The series is a six-book young adult fantasy run that came out around 2000 through 2002. It follows three sisters — Mairi, Isobel, and Kestrel — who live in a remote Scottish highland setting where magic is real but mostly hidden from ordinary people. The core premise involves them discovering they are "daughters of the moon," which in this universe means they carry some kind of inherited magical ability tied to the lunar cycle and to older, darker powers lurking nearby. The books are: The Darkening Woods, The Moonstone, The Silver Branch, The Red Rose, The Green Knight, and The Blue Star. Each one focuses on a particular magical artifact or trial. The tone leans Gothic rather than lighthearted — these are not feel-good fantasies. There are real stakes and some genuinely unsettling scenes, especially in the later books.
Where to find Daughters Of The Moon Lynne Ewing
The books are still in print through secondhand channels. Amazon Marketplace, AbeBooks, and ThriftBooks all carry used copies regularly. A complete set in decent condition usually runs somewhere between $30 and $60 depending on whether you mind mild shelf wear. New old-stock copies occasionally surface on eBay from sellers clearing out personal libraries. If you want digital, the books are available on Kindle and sometimes through local library apps like Libby. I've had mixed luck with the Kindle versions — some editions have formatting quirks where chapter breaks disappear or page numbers get garbled. The paperback originals are more reliable if you're reading on a device that supports image-based text extraction. For readers outside the UK and US, check whether your national library offers interlibrary loan for these titles. They are out of print from the original publisher (HarperCollins imprint) so new stock is limited, but older copies circulate frequently between libraries.
Reading Order and Structure
Read the books in publication order. The narrative builds character relationships and magical mechanics sequentially, and skipping around breaks the internal logic. Mairi is the primary POV character in the first two books, then the perspective shifts more evenly across the sisters. The later books assume you already know the rules established early on. Each book is roughly 200 to 250 pages. That's intentionally paced for a YA audience — not dense, not rushed. The worldbuilding is sparse by design. Ewing doesn't pause to explain every magical rule. She assumes the reader will track patterns through context. This works for most readers but can frustrate people who want systematic magical frameworks.

What Makes This Series Different From Similar Titles
The closest comparisons are the "witch sister" subgenre that was popular in the early 2000s — things like Thornwitch or early Earthsea adjacent titles. The key difference here is that the sisters' powers are not universally helpful. The moon magic comes with conditions: it weakens during certain phases, it can attract unwanted attention from darker entities, and using it has physical costs. This isn't a power fantasy. The characters get hurt, make mistakes, and sometimes fail to solve problems cleanly. Another distinguishing factor is the setting. The Scottish highland backdrop isn't decorative — the landscape actively shapes the magic system. Certain locations amplify or dampen abilities. Weather matters. This creates natural tension that plot-driven fantasies often manufacture artificially.
Known Issues and Limitations
The series has a pacing problem in the middle books. The Silver Branch and The Red Rose both drag slightly because the central conflict stretches across more pages than the plot really needs. The mysteries take too long to resolve, and some character interactions repeat themselves. If you're reading for plot momentum, expect a lull around book three or four. The ending of the final book leaves some threads intentionally unresolved. Ewing hinted at continuation but the series ended without a tie-off for every character arc. Some readers find this satisfyingly ambiguous. Others find it incomplete. It's worth knowing before you commit to the full set. Also, the representation of Gaelic culture and language has been called into question by some readers. The terms and references are respectful in intent but not deeply researched. If cultural authenticity matters to your reading experience, keep that in mind.
Who Should Read This and Who Should Skip It
This works well for readers aged twelve and up who enjoy atmospheric fantasy with a slower burn. It's not for readers who want fast action, complex political intrigue, or extensive worldbuilding encyclopedias. The magic system is small and focused, not expansive. The character development is the real draw. If you've already read The Little Bookroom series by the same author, you'll recognize similar tonal choices — domestic spaces as magical anchors, sisters as the core unit, and a general sense that the ordinary world holds more wonder than characters initially expect. If that sounded dull to you, this probably will too. For a similar experience with tighter plotting, consider The Iron Druid Chronicles by Kevin Hearne if you want something more adult-oriented, or Wicked Lovely by Melissa Marr for a darker contemporary take on fae-adjacent themes. If you want the sister-dynamic specifically, The Girl of Fire and Thorns by Rae Carson shares some structural DNA though it's set in a completely different world.

Practical Tips for Getting Through the Series
Don't rush. These books reward slow reading because the atmosphere carries as much weight as the plot. I've seen people finish the first two books in a weekend and then drop the series because they weren't invested in the slower third act. Give it until at least the midpoint of The Moonstone before deciding whether it clicks. Keep a simple notes sheet if you want to track the lunar cycle references. The moon phases matter to the plot more than the text explicitly states on first read. Writing down when each book's events occur relative to the lunar calendar helps spot connections you might otherwise miss. Listen to audiobook versions if available through your library. The narration quality varies by edition, but a well-performed audio version can highlight the atmospheric writing that sometimes gets lost in silent reading. The BBC Radio adaptations of Ewing's work are worth seeking out separately if you can find them.
The series is worth reading if you want something that doesn't treat its young audience as incapable of handling moral ambiguity. The characters face real choices with real consequences. That's not always comfortable, but it's honest storytelling for that age group.
