Deep Space — Richard A. Lupoff

"Forever City" is the story of Alfonso Ivanovich Petrov and Mariel O'Hara, two members of a space-bred generation to whom Earth is little more than their ancestral home, a legend of the past. When Mariel's brother, Dylan, disappears on an expedition to explore the distant Oort Cloud that circles the sun at a distance far beyond the orbit of the most remote planet, Mariel refuses to give him up for lost. Along with Alfonso, Mariel explores deep space in search of her missing brother! Also included in Deep Space: A Novel and Two Novelettes are Richard A. Lupoff's acclaimed, Nebula-nominated stories "After the Dreamtime" and "Sail the Tide of Mourning."
