An action-packed military science fiction series from #1 Amazon Bestselling author John Spearman.

A New Captain. A Repurposed Cruiser. A Crew No One Wanted.

Fresh off a heroic tour on the frigate HMS Essex, Commander Jonah Halberd is rewarded with an unexpected promotion to Captain and an even bigger challenge: command of HMS Cumberland.

But this is no ordinary heavy cruiser.

The Cumberland is a captured enemy vessel with experimental technology, including powerful rail guns the Royal Navy abandoned a century ago.
Halberd's new command comes with more than just unfamiliar systems. His crew is a volatile mix of raw recruits fresh out of basic training and officers cast off from other ships—the ones nobody else wanted.

He must quickly whip this troubled crew into a fighting force to face the Rodinan Federation as they are sent deep into enemy territory to destroy a vital orbital station and rescue a high-profile political prisoner.

The odds are stacked against him, but good captains make good crews, and Halberd is determined to unlock the Cumberland's hidden potential.

Gallantry in Action is the first book in the thrilling Jonah Halberd Series. If you love classic military sci-fi with compelling characters, innovative tactics, and explosive space battles, you'll be captivated by John J. Spearman's fast-paced adventure.

Join HMS Cumberland on her maiden voyage and discover what it truly means to lead, to fight, and to win against impossible odds.
