Samantha Argent and her Hunter-Killer team were in hot pursuit of "The Catalog" -the only known "knock list" of all Ultra-Sapiens, their powers and their current locations. To their stunned surprise, they found the Catalog in a remote ranch house in Montana -not in electronic form, but instead imprinted directly into the genetic code of a second-generation Ultra-Sapien named Ellis. Ellis' parents sacrificed their lives to protect Ellis from abduction and were willing to sacrifice Ellis' life as well rather than have their boy fall into Samantha's hands.
