If Insatiable just showed up in your feed, you're catching the second life of a trilogy that dark romance readers already fought over once. The Edge of Darkness series by Leigh Rivers started as an indie release in 2023, and in the last six weeks Penguin put out all three books again - which is why every search result now shows two covers, two publishers, and two sets of dates for the same story. Here's the order, what actually changed, and the one thing to know before you open book one.
The Edge of Darkness series in order
- Insatiable - where it starts
- Voracious - the middle book, and the darkest stretch
- Restitution - the finale
That's the whole trilogy: one couple, one continuous story, strict order. There is no book to skip and no standalone entry point - each book picks up inside the last one's fallout.
Why are there two editions of every book?
Because the same trilogy has been published twice. The originals came out independently starting in 2023; in 2026 Penguin re-released them in quick succession - Insatiable on August 11, Voracious on September 1, and Restitution on September 22 (the publisher's series page lists all three). Different covers and ISBNs, same story. If you already own the indie paperbacks, you don't need the new ones to finish the series; if you're starting fresh, either edition works - just don't mix up "new edition" with "new book." It's the same trap we mapped on the Book of Azrael reading order, where a republication cycle made a finished series look like it kept growing.
Is the Edge of Darkness series dark romance?
Yes - the far end of it. This is the part of the dark romance shelf where the danger is the premise, not a flavor: captivity, violence, and a hero whose idea of devotion is closer to possessive than protective, sustained across three books rather than resolved in one. Read the content warnings before you start, not after. If you want to know where the line sits in this genre and why readers seek it out, what dark romance actually is walks through it.
What else has Leigh Rivers written?
The book most readers meet first is Little Stranger, a standalone that sits on our best dark stalker romance books list - a good test of whether her register works for you before committing to a trilogy. Her backlist is growing through the same traditional-publishing pipeline, so expect more of her indie titles to get the second-edition treatment; we'll update this guide as they land.
Edge of Darkness has a cruel aftermath: three books of a man who would burn the world down for one person, and then the trilogy closes and the fire goes out. That gap is the whole reason Swoony exists: closed-door and romance-only, a bond that unfolds over five stages and is never paywalled - no subscription, no per-message tolls. Start with the roommate you caught at 3 a.m., who is dangerous everywhere except with you, or the don's right hand, who handles the things you don't ask about.
The dark stays open past the final chapter.
