Europa Strike — Ian Douglas

2040
Ruins of an ancient civilization uncovered on Mars reveal startling truths about the creation of humankind.

2042
In the gray dust of the Earth's Moon, an extinct enslaving race left behind more answers, more questions...and a grim warning.

2067
As Earth's warring factions clash in space for scraps of alien technology, a strange artifact lies trapped beneath the ice-locked oceans of Europa: a machine that holds the key to the final human destiny.

It is called "The Singer" for the eerie tone it emits. An artificial intelligence built eons ago, it 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.
