The Galaxy Chronicles

A hero to all except himself, Alton Wallis has lost his enthusiasm for command. The only captain to return from a tour with 98% of his crew intact, was unprecedented and as yet unmatched. But his past demons continue to haunt him. Now, an alien weapon of terrifying power has destroyed Aldonia and all 26 billion people on the planet. Now, forced to take command of an untested ship and an untried crew, they race across the galaxy to face the threat. If they succeed, humanity might still have a future. But if they fail, it could mean the end of EVERYTHING.
