Book excerpt: Life was pretty simple for Infinity Richards as a teenager in a private school in Baltimore. Then she woke up to discover that she'd spent the past two years in a prison camp. Now she and her friends are faced with a trek across a forbidding landscape scarred by a surprise nuclear attack on the United States. Their journey will lead them past hot zones, warlords, "crazies," occupying Coalition forces and an assortment of allies and foes. It may take her years to get to Camp Zion in the West where her father is reorganizing American forces to take back their country. But in the meantime, her journey across apocalyptic America will turn her into someone stronger, smarter and more courageous than she ever imagined she would be. More than three centuries ago, John Bunyan wrote Pilgrim's Progress, second only to the Bible in readership. Now Infinity's Reach revisits the challenges and lessons of the original Pilgrim's Progress in a totally new and exciting setting.
