Wren Ashvane and Kael Corwin were never supposed to fall in love. Their marriage was a treaty, not a choice?two warring houses bound together by an ancient curse, sealed in ink and blood to end a feud neither of them started. She was raised to read a room before it could hurt her. He was raised to win wars his family had already lost the right to fight. Neither expected the other to become the one person they could finally stop performing for.

But the bond between them was never as simple as it looked.

When a body turns up wearing evidence that shouldn't exist, Wren's forensic precision and Kael's hard-won instincts pull them into an investigation neither house wanted started?one that unravels a conspiracy older and far more dangerous than the war between Ashvane and Corwin. Someone has spent generations manufacturing the hatred between their families, profiting quietly from every funeral. And the deeper Wren and Kael dig, the clearer it becomes: their marriage was never the problem Concord promised to solve. It was the weapon someone else built to keep solving it for them.

Across four books and years of investigation, betrayal, and a partnership that becomes the realest thing either of them has ever had, Wren and Kael have to decide what's actually true?about the houses that raised them, about the institution that's supposed to protect them, and about each other. Trust, once broken, doesn't come back because two people want it to. It comes back because they choose it again, deliberately, every single day, with their eyes open.

The Last Binding is a complete four-book saga of arranged marriage, slow-burn devotion, and a mystery that goes all the way to the foundations of the world Wren and Kael were born into?for readers who want their romance hard-earned and their conspiracy to actually pay off.
