Cradles of Gravity

Colonel Riza Emberfell is a living legend.

Her kill count is in the tens of thousands. In her heavy black armor plating, she’s almost seven feet tall. To most humans that meet her, she looks like an alien demon—if they ever see her at all.

She also occasionally follows cats to complete objectives.

The mission is simple: An asset has spent months undercover studying a horrific bioweapon. Extract both the agent and the sample, recover the prototype cure, and get the hell off the planet.

The asset: Major Elias Blackwall—a quiet field medic with a warm personality—and the only person who’s never looked at Riza with fear. He doesn’t see a weapon or a legend—she’s just his commander and friend.

And she’s surprised how much that disarms her.

Battlefield Heartsurgery is the perfect high-octane, action-packed prequel to start your journey in the Cradles of Gravity universe. It follows two fan-favorite side characters six years before the main story begins. No prior knowledge is needed—just hop on in and enjoy the violence. Things get dark, characters get vulnerable, and a lot of enemies die. And underneath it all, the foundations emerge of a partnership that will one day shake the stars.
