The Thornbound Ruin: The Thornbound Pact - Book 6

By Avery Nightwell

The final task was never meant to be survived.

Mara Vey has stolen relics from fae courts, outrun death, and endured a pact that punishes distance and feeds on secrets. But the third and final trial drags her and Caelan Thorn into something older than law-something the Thorn Court buried for a reason.

Deep beneath the world, the Ruin Below waits like a living mouth. It remembers Caelan. It remembers what he refused to become. And it demands a price for every step forward.

To win, Mara and Caelan must return with the Heart of the Ruin before the gate seals-without unleashing what the courts used to control pacts like theirs. But the Ruin doesn't just test courage. It feeds on regret, desire, and unspoken truth... and it offers them exactly what they want most.

If Mara takes the Heart, she may become the next seal.

If she refuses, the court will claim her anyway.

Because this time, survival isn't enough.

They have to come back holding power the court can't control... and live long enough to keep it.

In this installment, you'll find:

- Dark fae court politics and a deadly final trial

- A magically bound pair forced to choose each other-again and again

- Gothic descent, horror-tinged romantasy tension, and high-stakes vows

- A hard-won claim that turns them into the court's newest enemy
