Star System Midway: Fleet Opposed Invasion

They come from the Constellation of the Devil every few thousand years to destroy all sentient life. This time, they are in for a surprise!
Book 3 of the Evidence of War series finds the humans and Restans hoping to spring the trap on the Amferians. Also the humans, led by Admiral Hooker on the converted Star-Guardian Ambassador, are trying to convince the transplanted Neanderthals, now known as the Batkans, to join the fight. 
Meanwhile, the Amferian devils have sent a powerful fleet against one of the Batkan colonies, and only an old Star-Guardian, a brand new, untested Star-Guardian, and a small squadron of Restans are in a position to intercept them.
A larger still enemy fleet is gathering, but will their next target be the planet code-named Midway, where the trap will be sprung, or will they divert directly to Restas or even Earth?
