Heritage Trilogy, The #3 - Europa Strike

It is called "The Singer" for the eerie tone it emits. An artificial intelligence-built eons ago may ultimately solve the mystery of the vanished alien races responsible for the birth and development of humanity. But after decades of war, the hostile nations of Earth care more for power than for knowledge. And now all that stands between the coveted Al and an all-out Chinese assault is a vastly outnumbered contingent of U.S. marines, dug in beneath the baleful red eye of Jupiter. As terrifying events light years distant begin to converge---with confrontation imminent and annihilation inevitable---a secret history of creation and doom must at long last be contended with...if humankind is to finally claim its glorious heritage among the stars.
