Echoes of Earth

On an alien world a very long way from home, Peter Alander is going out of his mind. The Frank Tipler is just one of a thousand survey vessels sent out into the bubble of space surrounding Earth, seeking habitable worlds and signs of advanced life. Its crew has stumbled across artifacts left behind by a benevolent trader species, but the decision to study them is fraught with danger and uncertainty. The Tipler's crew consists of forty flawed electronic copies of human beings, some of them profoundly damaged—and Earth stopped responding to signals over a century ago. Caught between madness and political machinations, Alander stands on the brink of what might be the greatest discovery humanity has ever made—and a gift that humanity can't afford to accept.
