The Phantom in the Deep (Rook's Song Book 1)

Ten years after mankind has been wiped out from the universe by a techno-organic race known as the Cerebrals, a lone pilot, call sign “Rook,” stands alone in an asteroid field in a distant part of a spiral arm of the Milky Way Galaxy. As they close in around his home, ready to extinguish humanity once and for all, Rook stumbles upon a possible weakness in the Cerebs. One that humanity never discovered in time. Using strategies garnered from the Academy, as well as from his days as a Chess champion, he plans to make a last stand worthy enough to demonstrate the imaginative power of Man.
