Query: Great debut novel, profound wonderful and disturbing

Mary Doria Russell did some outstanding work in this debut novel. The Sparrow is a sci-fi fans dream, as it hits so many disciplines (astronomy, anthropology, aerodynamics)...But it is also a storyteller's dream, as the characters truly do live among the pages...By the time I finished this book, I was ready to cry for Emilio Sandoz, the sole survivor of the Rakhat expedition...The trauma of the entire experience is a parallel to the down-to-earth lives of everyday people, whose faith in God, family and country comes under fire every day...This is one of the best books I've read in a long time...Looking forward to reading Children of God...
