An Alien Rubicon

Lieutenant Colonel Myles Webb of the American Federated States Space Forces and a small Fleet of human ships are preparing to journey to the Centauri Star system where the Cheeb'Arr lurk and now call home. But he will not make the trip alone, since man's ally, the Hee’Umana, will also join him in facing off with the enemy. The odds of them being victorious against their foe grows larger as time passes, since their hesitation merely gives the Cheeb'Arr ample time to reinforce their position.
As the small Terran Battle Fleet and its allies are about to depart from the Sol system, the Cheeb'Arr make their presence own once more. But this time they employ new tactics, which man and their ally the Hee'Umana have never seen before. Now the Fleet must postpone their journey to the Centauri system until they are certain that the fortifications scattered throughout the Sol system are sufficient to halt the new Cheeb'Arr attack. If the newly constructed fortifications are not sufficient, they must remain behind and help eliminate the threat. But as Lieutenant Colonel Webb and the Terran Battle Fleet battle the presence currently within the Sol system, they are unaware that there are other plans in the works by the enemy. The Hee’Umana is harden to face the unknown and they suspect a trap, when they witness the Cheeb'Arr's new tactic. But will that be enough to prepare them for what is about to come?
