Synopsis: From the Back Cover of the Ace edition: "A leaper in shining armor - When the blue light fades after his latest Leap, Dr. Sam Beckett finds himself wielding a sword - and facing a man in full armor! No, Sam hasn't leaped into the court of King Arthur. He's jousting his way through a medieval recreation group, battling for the hand of a fair lady. But swordfighting isn't the only challenge Sam faces. A sinister new player has entered the game. Someone who threatens not only the Project, but Sam's life as well... Another leaper."
