Fleet At Whelming Tide Box Set - Fleet At Whelming Tide

Now all three books in the series are available in one box set! After the defeat of the Amferians, the human fleet is at full strength with more ships under construction. These include a new class of Star-Guardians called the Galaxy-class. There is a lot of pressure to now "stand down" and even mothball some of the older ships as public opinion comes to believe the threat from the stars is over. But as the Space Fleet command struggles with this public relations challenge, a new threat emerges.
Not in the form of a new alien species, but one humans have been dealing with for centuries. The Grey Aliens attack a human pod ship enroute to the colony planet Alpha. Supreme Commander Admiral of the Fleet Tallie Talbot decides we've had enough of their meddling, and orders War Plan Grey dusted off and activated. As operations are put under way, though, a very large mystery fleet appears in the ruins of the Amfero system, surveying the destruction wrought by the humans there in the last war.
Where did this fleet come from, and what is their intention?
