The first three books in the Obsidiar Fleet series are now available in this omnibusThe Vraxar have come. Their advance fleet is vast and they are definitely not friendly. Their aim isn't to settle and conquer, simply to bolster their army with the species they defeat before they move on.
Now it's humanity's turn. Join a cast of the Space Corps' finest as they come together to ensure the human Confederation will not be just another stepping-stone for the murderous Vraxar.

Unfortunately, his opponents are vastly superior in numbers and they don't care if they live or die. Fleet Admiral John Nathan Duggan - the most experienced man in the entire Space Corps.
