When it comes to hitting his target, Spencer Blackwelder can't miss. But when it comes to hitting the mark in other areas of his life, his aim is way off, which is definitely a problem when you're a military sharp shooter preparing for war with an alien species. As penance for past mistakes in friendship and in love, Blackwelder makes the bold choice to relocate to Fort Felix, a military base on Neptune's moon, a decision that could end up costing him his life. Once there, he meets: Juan Miguel Ar?as, to whom he takes an immediate liking; Vernita Burton, a true friend; and the men and women of Brant Squad, a group of lovable losers that he eventually takes under his wing. Blackwelder is surprised to discover he has something to live for again, but all of that is threatened when war finally arrives on Fort Felix's doorstep. Can Blackwelder find the hero within in time to save his squad, his planet, and the man he loves?
