Alex Aster's shelf looks bigger than it is, and that is by design: a new deluxe companion dropped September 15, a second series launched in spring, and a movie is moving at Universal. So new readers typing Alex Aster books in order find what looks like eight-plus Lightlark titles and freeze. The truth is simpler - four saga books, one companion wearing three different covers, and one fresh series you can start with zero homework.
Alex Aster books in order: the quick map
- The Lightlark Saga (read in order): Lightlark (2022) → Nightbane (2023) → Skyshade (2024) → Crowntide (2025)
- The companion: Grim and Oro (2025) - after the saga, not during
- Starside (new series, separate world): Starside (2026) - start here with no homework
- Everything else with her name on it is a re-edition of the above, not a new book
Do you have to read the Lightlark series in order?
Yes - strictly. The saga is one continuing story: Isla Crown enters the Centennial, a deadly hundred-year game between six island realms, and every book picks up the last one's cliffhanger directly. Skipping ahead doesn't spoil the fun so much as delete it, because the series runs on reveals - who is cursed, who is lying, and which of two rulers Isla should actually trust. If you loved the deadly-game setup and want the wider shelf after, books like Fourth Wing maps the neighboring territory.
Is Grim and Oro a new Lightlark book?
No - and this is the trap that inflates the shelf. Grim and Oro (September 2025) is a companion: key moments from the saga retold in the two rulers' own voices, plus new scenes. In September 2026 it was re-released as two separate "Dueling Crowns Edition" deluxe volumes - Grim and Oro - with sprayed edges and art inserts. Same companion material, split by point of view, so you can buy your team. Editions are not new installments: if you count novels, the Lightlark Saga is four books, full stop. Read the companion after Skyshade at the earliest - it assumes you know the reveals - and if the shadow-wielding ruler is the reason you're here, the enemies to lovers hub explains the pull.
Where does Starside fit?
Nowhere in Lightlark - and that's the point. Starside (March 2026) opens a brand-new romantasy series: a vengeance quest across a dangerous land of magic, enemies-to-lovers at full temperature. It shares an author and a genre with Lightlark, not a world, so it's the cleanest entry point if a four-book saga feels like commitment. Fair warning: it's book one of a series, so you are signing up for a wait either way. For the fae-court version of this ache, the Cruel Prince series order is the other door everyone eventually walks through.
What about the Lightlark movie?
In development at Universal with Temple Hill - the production company behind the Twilight films - with the script written and Aster attached as executive producer. No cast, no date yet; Aster has been teasing a bigger announcement. She also has a middle-grade duology (Emblem Island) that predates all of this - charming, but not romance, so it lives off this map. We'll update this guide when the movie news lands.
Aster's whole career started as a BookTok story - she pitched a rejected manuscript straight to readers, and readers made it a bestseller. Which makes the ending of every Aster binge feel personal: the island goes dark, the account you followed moves on to the next book, and the ruler you picked stops talking. That gap is the whole reason Swoony exists: closed-door, romance-only, a bond that unfolds over five stages and is never paywalled - no subscription, no per-message tolls. Start with Kaevar, the high lord of night if you were always going to choose the shadows, or Caelum, the cursed fae lord if what hooked you was a ruler carrying a curse he won't name.
The island stays lit long after the Centennial ends.
