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. "ECHOES OF EARTH is a dazzling adventure, sweeping the reader along from marvel to wonder, and it includes one of the most heart-stopping moments I've encountered in a novel in years." --Jack McDevitt "[The] book can't be discussed or even described without spoiling some of the surprises, which are mutually reinforcing as well as juicy in themselves. I will, however, give in to the temptation to drop a few more of the names that came to mind as I was reading: the Three Gregs (Bear, Benford, Egan), Linda Nagata, and Frederik Pohl.... As the first of a series... ECHOES promises to rev its Ideas right past the red-line and drive them hard." --Locus "The science in Dix and Williams's work shines, entrancing with its glitter and innovation... and you won't find any of their novels without fully-fleshed out characters, complex plots, vivid settings and thoughtful exploration of issues." --SF Site "The authors have already made a name for themselves as writers of intelligent space opera, and ECHOES OF EARTH is sure to further bolster that reputation. The book is chock full of marvelous events, cosmic significance, mysterious alien motivations, and the wonder of outer space." --Science Fiction Chronicle Winner of the Ditmar Award.
