Orphan’s Triumph by Robert Buettner
Jason Wander has had to deal with a lot. First the Slugs wiped out his family, then they tried to go after his planet. Now he’s going after them…
After forty years of fighting the Slugs, mankind’s reunited planets control the vital crossroad that secures their uneasy union. The doomsday weapon that can end the war, and the mighty fleet that will carry it to the Slug homeworld, lie within humanity’s grasp.
Since the Slug Blitz orphaned Jason Wander, he has risen from infantry recruit to commander of Earth’s garrisons on the emerging allied planets. But four decades of service have cost Jason not just his friends and family, but his innocence.
When an enemy counter stroke threatens to reverse the war and destroy mankind, Jason must finally confront not only his lifelong alien enemy, but the reality of what a lifetime as a soldier has made him.
