Armageddon's Children (The Genesis of Shannara, Book 1)

Logan Tom is doomed to remember the past and determined to rescue the future. Far behind him lies a boyhood cut violently short by his family's slaughter, when the forces of madness and hate swept our world after decadent excesses led to civilization's downfall. Somewhere ahead of him rests the only chance to beat back the minions of evil that are systematically killing and enslaving the last remnants of humanity. Navigating the scarred and poisoned landscape that once was America and guided by a powerful talisman, Logan has sworn an oath to seek out a remarkable being born of magic, possessed of untold abilities, and destined to lead the final fight against darkness.
Across the country, Angel Perez, herself a survivor of the malevolent death-dealing forces combing the land, has also been chosen for an uncanny mission in the name of her ruined world's salvation. From the devastated streets of Los Angeles, she will journey to find a place - and a people - shrouded in mystery, celebrated in legend, and vital to the cause of humankind...even as a relentless foe follows close behind, bent on her extermination. Meanwhile, in the nearly forsaken city of Seattle, a makeshift family of refugees has carved out a tenuous existence among the street gangs, mutants, and marauders fighting to stay alive against mounting odds - and something unspeakable that has come from the shadows in search of prey.
