Orbit is delighted to announce we’ve acquired a brand-new fantasy series from Melissa Caruso, the critically acclaimed author of the Swords and Fire trilogy and the Rooks and Ruin trilogy!

Perfect for fans of Vivian Shaw and Genevieve Cogman, this action-packed series kicks off with The Last Hour Between Worlds. Follow a star investigator and her rival as they journey through layers of reality to save the world as they know it in this exciting adventure fantasy about rival guilds, reality-bending magic, and unexpected mystery.

Read on for a bit more on what you can expect!

Kembral Thorne is spending a few hours away from her newborn, and she’s determined to enjoy herself at this party no matter what. But when the guests start dropping dead, Kem has no choice but to get to work. She is a Hound, after all, and she can’t help picking up the scent of trouble.

She’s not the only one. Her professional and personal nemesis, notorious burglar Rika Nonesuch, is on the prowl. They quickly identify what’s causing the mayhem: a mysterious grandfather clock that sends them down an Echo every time it chimes. In each strange new layer of reality, time resets and a sinister figure appears to perform a blood-soaked ritual.

As Kem and Rika fall into increasingly macabre versions of their city, they’ll need to rely on their wits—and each other—to unravel the secret of the clock and save their home.

You don’t want to miss The Last Hour Between Worlds when it lands in bookstores in Winter 2024. In the meantime, follow Melissa on Twitter @melisscaru and find out more at melissacaruso.net.
