Space Invaded. Dar's Adventures in Space, #4

The peaceful planet of Nerit is under attack by the savage Graalix. Pleas for help have gone largely unanswered throughout the Ontarrin Galaxy. Only Satiris, home of the peace-loving Satirens, answers the call. The Satiren High Council is at a loss. They must aid their allies, for the Neritians are the ones keeping Satiris alive. Both species lack weapons and warrior skills. They desperately need someone with fighting experience.
Dar Meltom is no stranger to conflict. As captain of the freighter Marsuian, and a half-breed, he's been fighting all his life. The high council convinces him to command a fledgling army that has never tasted battle. Dar has reservations from the very beginning. He enlists Robert, his Earthling stepfather, who has a unique knowledge of the invaders. Together they hatch a risky plan that means certain death.
As the battle begins.Dar and his ragtag army of Satirens and a few Lanterians plunge headlong into a wormhole and tempt fate. What they find on the other side is death, galactic annihilation, and something that will change their lives forever. Dar and Robert must race the clock, battle the Graalix, and return safely to the Ontarrin Galaxy with precious cargo onboard.
