Grave and Hollow (Hellhound Academy #4) Release Date: September 4, 2025

Published

When you’re dead, you’ve got nothing left to lose.

Robin is coming for her enemies, one mission at a time.
The Circle took everything—her memories, her life, and far too many others. But Robin isn’t hiding anymore. Her squad’s first mission sends them into Grave to Hollow, a sunken training ground where the lost are still restless and the dead don’t stay buried.

Hidden just outside Austin, the Hollow is one of many scars left behind.
But if this place was abandoned—why is someone still calling the dead to it?

Cadets who never woke up. A past that won’t let go. And something old stirring beneath the surface.

Time to reclaim what was stolen.
Dive into Grave and Hollow—the fight starts here.
