A galaxy on the brink.
An enemy that can't be stopped.
And a trusted ally who might be the greatest threat of all.

Nate Arturi thought he understood the stakes. After years as an Excalibur Knight—saving planets, battling swarms, and facing down more ancient evils than he cares to count—he believed the war was finally turning their way.

He was wrong.

Now, with the Synth swarms multiplying faster than ever, Nate and the crew of the Camelot race to uncover answers buried deep behind enemy lines. Their only hope? A desperate gamble to confront the swarm from within—where the line between science and suicide blurs, and the secrets Nate uncovers could either save the galaxy or destroy it.

But the Synth aren't the only threat Nate faces. As the dark forces within his own Excalibur tighten their grip, he must decide how far he's willing to go—and how much of himself he's willing to sacrifice—for a galaxy that may already be doomed.

With soaring stakes, snark, and searing sci-fi action, Darkest Knight is the gripping next chapter in the Excalibur Knights Saga. Perfect for fans of epic space opera, Arthurian legends, reluctant heroes, and razor-sharp banter.
