Solar Whisper

A city of peace. A whisper of chaos. A legacy at stake.

Lyonesse is a beacon of unity in a fractured galaxy, a space-based city-state built on the dream of integration and peace. For Danny Andela, it’s not just home—it’s her mission. As a fierce advocate for dissolving old feuds, Danny has spent decades working to unite the Carinad, Terran, and Bai worlds.

But something is wrong in Lyonesse. A series of weird malfunctions—some laughable, others deadly—hint at deeper troubles within the city’s core. As whispers of unease ripple through its gleaming domes, Danny battles growing paranoia, questioning allies, and doubting the systems she once championed. Her fight for peace becomes a desperate race to uncover the truth before a catastrophic failure silences Lyonesse forever.

Or should she? Is Lyonesse the shade of an old enemy? Danny must confront ghosts—and the terrible echoes of the war she thought she’d left behind. Will she stop the chaos in time, or will Lyonesse become the spark that reignites the galaxy’s divisions?

Praise for Cam’s previous two Hammer series:

Wow, what a ride.

A complex and interesting series.

Deep complex, wonderful world building and character development.

…it was what happened to the cast of characters that made this series so enthralling for me.

An incredible set of stories. There is nothing else out there like this.

A sprawling epic space opera spanning many long decades.

I am in awe of the writing ability and imagination of Cameron Cooper.

Brilliant and intricate.

…it was one helluva run. The ending is an extraordinary coming together of the people.

I am so enthralled with the series that I am impatient for the release of the next book.

Cameron somehow describes scenes in ways that make me feel like I am actually present

This story truly does justice to the legacies of the greats, like Orson Scott Card and Frank Herbert.

Edge of your seat action will keep you captivated until the final page!!

Cooper is a masterful storyteller

This is sci-fi at its best.

This story, and the entire series, truly does justice to the greats of science fiction.

Cameron is an excellent sci-fi writer, but this series is way beyond anything I anticipated
