"Alternitech" sends prospectors into alternate but similar timelines where tiny differences yield significant changes: a world where the Beatles never broke up, or where Lee Harvey Oswald wasn't gunned down after the Kennedy assassination, where an accidental medical breakthrough offers the cure to a certain disease, where a struggling author really did write the great American novel, or where a freak accident reveals the existence of a serial killer. Alternitech finds those differences-and profits from them.
